Player Experience Highlights
Community Insight:
It was awesome we loved the storyline and how kirell acts and just all of that, but we feel there should be a specific interactive novel for KIRELL shes an awesome character and we just feel itd lure more viewers in.
We played this game years and years ago wants recently came back to it just to see if it was good or not and its amazing the story is so awesome and the gameplay is cool we only can complain about is the ticket system but it doesnt bother us to much.
To say this game is interesting and meaningful, you can learn new experience with different characteristic. Its free, bring back nostalgia feeling, remind us of the robot game which we forgot its name, its like finding object and interact with the character leading the robot story. This game is similar, so keep up.
Nu ai cha chi th toy bt m ng we cng ng Agro ng nht vi.
We absolutely love this game so much, we don't think there's one thing we don't like. Even with the characters, maybe you don't like them or maybe you just haven't fully met them. They're not half written or totally predictable, they're lovable and relatable. Also it's a story game is the story good? YES oh our gods we love the story. It's seven days but we swear we could replay it like a lifetime. It's not one sided there's no 100% right, wrong, good, nor bad. It feels real and we love it because it's so strange still.
We dont ever write but we really do like this game. We love the story and the compatibility between characters, everyone has their own mission and mindset which really brings out the diversity. Its unique and we enjoy replaying this game from time to time. We played this a couple years ago so Im glad to play it once more.
This is entertaining and different. We really enjoyed it and would certainly check out other visual/interactive novels by this developer. Ads to earn points for, "Tickets," were not too intrusive and there were less /shorter ads than on other apps.
The game is great. All of the compliments in all of the reviews are true, times ten. But there is two minor problems that, if fixed, could increase the amount of players. So, first, the ads encourage LGBTQ+, but our family and we just don't believe in it, along with MANY other people. With all due respect to anyone who thinks otherwise, we think using neutral ads would help. Many people such as ourselves delete games which have these kind of ads. All of them would play if you fixed it. So, that would be a smart move. The second thing is, it says watch ad to get 40 tickets, but its actually 2 ads. Please could you fix this? If not, at least turn the 40 to a 60, or at least 55. That would make it easier to stock up on tickets, allowing smooth gameplay. We know this is an earful, but it would help EVERYONE if you acted on this. If not, that's okay, it's your game. But it would be nice if you could just consider it, please.
We absolutely love this game we normally dont write reviews but this game is so addicting and the story and art are amazing. We think we have a screenshot of every piece of art in here. We love the story and the underlying risk and unease as you play. How you have to contemplate every action and answer as to how it will effect the characters and the outcome. We love the backstory and the game overall. We would play it 24/7 if we could. Our only problem is the ticket system. We get that the developers have to make money somehow. It was fine for a while watching a 30 second add for 40 tickets isnt bad and Im normally fine with it. Our only problem is that the game stopped letting us watch adds. The buy ticket screen pops up and we go to click the watch an add for ticket button and it closes itself. It wont let us watch an add to get tickets. We dont know if this is on purpose or not but its starting to irritate us because Ive waited hours closed and opened the game but still nothing works and the problem persists. We love this game but Im really confused as to how we can fix this to keep playing. If not for this it would be 5 stars.
Ive only done episode one because theres no ads to get tickets from and its been several days now and still nothing.
Ive tried playing the game on two different phones and an iPad. And each time (on all devices) we got on the game, the app would close and go back to the Home Screen. Though we have managed to play it one time and we liked it so far. Please try and fix the problem. We think we might actually like the game.
Tickets make it hard to enjoy and remove the emersion in the story but the story is amazing.
WHY CANNOT PURCHASE FOR ONE PRICE INSTEAD OF TICKETING. TREAT ONE LIKE A 9 YEAR OLD AND THE WAY TO PLAY IS TO BE ONE AND ASK MOMMY AND DADDY IF we COULD BUY TICKETS TO MAKE A CHOICE. We AM KIDDING KINDA AND NOT 9 BUT IF THIS IS INTERACTIVE STORY WITH CONTENT LIKE DEPRESSION AND DYINGSHOCKED WHY 1555 TICKETS? ERICA IS ONE TO PLAY AND NO CONFUSION ON THINKING ITS FOR ADULTS EVEN THOUGH ITS NOT SICK LIKE MOST. We HATE ANIMATION. PLEASE LET ME KNOW LIKE WHAT STORY TO GO TO.
Each message takes >3 seconds to appear. In a text chat. Its painful. Gave up on Day One.
2 parte?,SEGUNDA PARTE POR FAVOR.
Both plot and characters are written very well. It was very easy for us to get attached to these characters. As of right now Im trying to find out how to make all the characters survive because we love all of them so much lol. Not only that, but we havent seen a plot line like this. This game is very unique, and we havent heard of a plot simular to this one. Ads were also placed well too, since this is a free game we expected lots of pop up ads, but they were only placed in the game so you can get more tickets, thus continuing the game. Which Im really glad about. Im also glad that this game advertises their other games because if this game is fun we know that the others will as well. 10/10 game.
It took a while for the game to let us in, but when it did, it was really interesting. The tickets are annoying though, Im completely okay with watching adds for commercials, but the adds arent working.
We thought this was the best game of our LIFE a 10!!!!!!!! Until we were excited and we ran out of stupid tikets and had to pay for that! Now it's a 0, YOU WERE REALLY EXCITED AND DISAPPOINTED ENOUGH Don't waste your time downloading this.
We love this game so fun loved it a little sad tho but really good <3.
Makes you think. We like the game so far seems like the first person you meet is the one you gotta kill.
Ok so we really dont write reviews on the games we played so often, but this one is good, we mean decent plot, totally free to play u can watch ads for couple of minutes and manage to collect 300 tickets or so, and the checkpoint thing which is really helpful, also the choices u make actually effect how the story will end and effect ur likability among each character. So yeah, a really good game in general, would recommend it for sure.
This game has us at the edge of our seat waiting for more because of all the tension but we ultimately ended up liking it a lot we didnt get along with most of the characters but we think Im going to go back and try again. We looked it up on a few platforms to see the other endings and the story is kinda sad if you think about it. Overall great story, characters, and build up.
Im at the beginning of the game and its already so good, we dont wanna spoil it but we highly recommend for people who wanna find an exciting game, if we could we would give this game a 5m star review.
We hadnt realized that Buff Studios also produced this game/visual novel of choices as well – only until we clicked to see what other games theyd made. This game was our reason for downloading Underworld Office – a game that, unfortunately is currently glitched to the point where we cannot continue. But 7 Days was a real gem, with your choices (unlike a lot of other games within this genre) actuality having a great impact on the ending you received. We finished the game and it wasnt the best ending, but it also wasnt the worse. We found the whole concept very intriguing,the idea of these strangers attempting to recollect memories of what they did wrong in life, so that they may try to redeem themselves in death (while in a state of purgatory). Also, the character interaction is great too, with your responses and actions determining your relationship with them. All of you have a secret mission, from what we remember, in which you must fulfil (one example we believe was that one of the characters must kill one of the others). We think your mission was In direct comparison to how you lived or died: if you were a good person who hadnt committed many misdeeds, your mission would be simple and easy to achieve. But if your transgressions were quite bad, the mission would be harder/more upsetting. Im pretty sure thats the gist of the game, and we know we really enjoyed it if we kept it upon completion. That nears we must have intended to replay it in order to receive a different ending. Ill probably do that now, and keep our fingers crossed that the developers help us to continue playing Underworld Office. Great work, guys, on creating some truly unique and enjoyable storylines.
We actually dont mind watching short ads to get tickets in order to read and play more of the story. The characters, art, music, story, and interface are all brilliantly done.
Keeps you engaged. Specially if you love reading comics Feels like reading a storybook but with an option to rewrite it yourself.
This game was so much fun but sad at the same time when we lost Balaam we almost cried even though we knew he was bing resurrected still we almost cried and then Argo we didnt then hilde we were sad but not crying then then we had to kill someone and we practically cried but we started balling our eyes out at the end because she woke up to ALL of by her bed and fact when we are writing this we are crying.
We dont usually write reviews but this game was so different and very interesting! It hooked us up and we were addicted and we still am! We love the characters, the story, and the choices that you have to make! Speaking of choices, we really like how every choice you make have consequences and will change the story. Thank you so much for making this incredible game! Our favorite characters are Argo, Hilde, and Kirell! Their names are very pretty and unique! :D Thanks again!!! :D.
We never write reviews but we HAD TO for this game. It touched us to a point where we cried when we reached the first ending, then immediately went back for more. From the get go, the story and characters grip you and youre left begging for more. Every character is so unique and multidimensional, we ended up loving all of them and we carry little pieces of them with us. Even Philio. We love the graphics, the sound effects, and most of all how you dont have to pay to get to the end. You can choose to watch ads, and otherwise they wont be thrown in your face like every other game out there. This along with the nuances of the story truly shows how much the developers respect the players, and Ill definitely be downloading and playing every single game they release.
Its a game that gives us what we want its just like we would expect from a choice based game and the only annoying thing is the ticket system which makes you watch an add for 40 tickets which is only 8 choices and each choose is 5 tickets but thats our only problem with all of their choise games.
This game is a fantastic, beautiful experience. We were completely enthralled and sucked in by the intriguing story and incredible artwork. We just discovered that the game is available for purchase as well, and we will be downloading it after finishing this review. This game is clearly a labor of love and worth your time.
When it comes to mobile games like these we always fear about the ticket system this game uses. While we the we find the ticket system annoying, It is one we prefer over some other ones. Allowing free tickets every minute for a 30 second ad isn't the best but it isn't the worst. We enjoy this over what we thought was gonna be a daily ticket system where we would then have to wait to play the game till the next day which we would hate because we love story games like these and hate the cliffhangers. Besides this though it is an amazing game. We only just started and the story is amazing and the characters are enjoyable. We 100% recommended you give this game a try if you enjoy tell tale games.
Didnt take long to intrigue us. Will update as we go along.
We are IN LOVE with this story, however you only get 200 tickets to start with, and we didnt quite count how many you waste each time you choose a decision but eventually you burn through them all and you need tickets to choose what you want say or do. And if your like us who is a bit impatient and dont really want to watch ads each time you finish 30 tickets each time then as much as the story is beautifully written and captivating. It mystery vibe and wanting to know more can only hold up for so long. We didnt finish the story but because of needing tickets and watching the adds we could honestly care less. Kind of how our desocupen in the game were all more like kill if they prove to be useless. But be a bit merciful. Anyways Love the story, dont like the ads. It wouldve been better had you just have to wait an hour or two for tickets.
You cant buy this game. You have to buy tickets or watch ads or make other purchases. It really detracts from the enjoyment of the game. We wish there were just a buy this game option.
Whenever we try joining Ill get kicked out for some reason so this game is not playable we Heard from a lot of reviews saying that this game is pretty good so three stars but please fix that bug.
Earning tickets is very time consuming and we get they want to make the game longer than it would be otherwise, but we only earn 40 tickets when we watch an ad and everybody else is saying they get 70. Also, a few times we entered our response, the game consumed way more than 5 tickets. We had exhausted almost all of our tickets by the end of day 1 which should have happened if responses cost 5 tickets a piece. There is also no way for us to contact support because the entire site is in Korean.
We say all of the great reviews and we thought we should try it out but we downloaded it and cant even get in the game.
Hasta ahora es uno de los mejores juegos que he jugado, la historia, la trama. Todo, y lo mejor de todo es que tiene finales alternos, incluso su desarrollo.
Usually wouldnt write reviews bc im to lazy but! This game can take that from us for a second wouldnt hurt.. We actually enjoy it very much, we love how we get to pick choices & that it matters in our favors.
Ur game is good but we wish where was some game play but thats fine its still good we also downloaded ur other game that was like this :).
Cool game! Hard to put down once you get invested.
We really liked this game our friend showed it to us we really like it but we just wish there were more ending but it is really fun.
We just love the storyline and the choices we get to make! All the characters have such an interesting background and the personalities! Plus lots of endings to discover and cute art! 5 stars, would recommend.
Everything about this game is great from storyline to the art the only bad thing is to keep on playing you either buy tickets or watch adds but we get that the have to do it because its a free game.
Por favor agreguen la opcin de subir tus partidas a icloud.
We've played this game before but we stop playing it at the part where balaam kill the guy.
You have died and lost all your memories, but the god of death sees you have unfinished business. You and a number of others are given tricky and morally challenging tasks to complete to be resurrected, and the story revolves around you completing your task while helping and meeting others and exploring your memories and feelings. The story is well explored, with good choices at every point, some of which even depending on previous choices. When paired with gorgeous stylized art and nice pacing (not too short, not too long), this is the perfect visual novel. Regarding the ads others have mentioned, we will admit they are a bit intrusive. You have the option to watch ads to continue playing or make microtransactions to buy yourself some extra time. $4 gets you 300 uninterrupted choices, but you will eventually have to go back and buy another package. This is a bit frustrating and could be improved upon by adding a one-time purchase. It might make less money than ads but we think more people would prefer to go for a one-time purchase than going through repeated transactions. We would pay anywhere between $1-10 for the full story! Regarding the app's features, here's a good list: -A timeline lets you see your past outcomes and travel to these checkpoints you've unlocked. -Profiles are given to all characters, featuring full portraits, details about them and their equipment, and everything you've learned about them so far. -Characters have "likabilities" that change with what you choose, and these can also be tracked in profiles. These scores are wonderfully incorporated and make real differences! -Upon finishing the game, you are freely allowed to go back and change some starting circumstances you had and make a fresh new experience and a possible new ending! Overall, the game is beautifully done and we can't wait to see more updates or games from the developers.
We find this game interesting and would like to see how it all goes.
