Player Experience Highlights
Community Insight:
Have been playing this game for 2 and a half years and have never and will never get tired of this wonderful game. 10/10.
Id love to see more content made for this game. Super cute and entertaining hehe.
Been playing for maybe 2 months now, genuinely super fun and you can get by with watching 0 ads but it rewards you if you choose to watch them! Its a perfect balance between being afk and having a strategy, and theres a decently active playerbase that will help you get out of the slightly boring early game. If you need tips definitely join the discord.
Only thing better would be 34rd.
If we use siri in the middle of a game, instead of being paused it will just freeze and then exit the game.
Updates take forever. New content takes a while. We left months ago and came back to a seal and sperm whale.
Progression is pretty much locked at around 2 hours in. We guess its the paywall. There isnt much to do without tedious grinding.
Hi guys, we are currently in stage 113 but we still can find frog shop? How can we find it? Thanks.
We have played this game for quite a while and am always hitting top 30 in pvp. We love this game, but it reflects how upset we can be to the developers. It is a game with lots of potential but they do not see it seriously. Heres some issues: 1. It is extremely time consuming. Each coop takes 17 minutes and a ticket is filled every hour. It takes several hours to spend your tickets. Not to mention there is also pvp and even chaos coop with the new update. There is no acceleration more than 2x even for top players. With the new update, it doesnt allow you to afk even though we can easily get pass the first several waves without doing anything. Suggestion: remove the afk punish or let the other player who is playing decide whether the player is afk. Add faster acceleration to coop. For example, 5x acceleration upon agreement by both players. 2. Constant delay and slow progress in new game content. You can purchase VIP in game, but unfortunately they do not add new content as promised. There is always a delay and it makes players feel like they are wasting your time to get your money for being VIP. Suggestion: Do not delay the update of new content, and give updates about future direction of the game. 3. Lack of communication with the players. The developers are super passive on hearing the voice of players. There are many player who love this game and tried to help improve it. Unfortunately many have left due to the passive and slow (even non) respond from the developers. We feel like they do not even care what the players think. Also, there are many bugs and the developers never give compensation for their mistakes. Suggestion: Respond to the suggestion. Listen to the players. Give compensations for delays in updates and bugs. There are still players waiting for the developers to wake up and treat this games seriously. We hope you can really listen to what the players have to say. By MyNickname.
We are a old player. We dont like the new update at all. U will get kick out because afk in co op ? When Im saving money why we have to do something.
We play a ton of games like these, but this game puts a slight twist to it. Im sure theres other games like this one, but since this is one of the first that actually put effort into their game we enjoy it. It can be a bit addicted but Ive played it longer then the other combine to level up kind of games.
Just started playing. Somewhat similar to random dice pretty good game nonetheless.
Super fun new game thats crazy addicting and is not pay to win! Love it and all our friends are hooked.
You hit the paywall in solo hard and quick. Co-op isnt any fun because you get overwhelmed so quickly. PvP is the only functioning thing thats legitimately fun and we hate pvp. The cash to gem ratio is terrible. $5 for a single platinum summon is insulting. You dont earn in game cash fast enough to keep up. You dont earn gems fast enough to warrant the amount of ads. If you do not get a quick hitting animal with decent damage early on youre pretty much up a creek without a paddle. There are other rng defense games who do this better and are far more fair in pricing.
Everything super expensive. Unlocked arena and all 5 duels were against people with full uniques and rares. Deleted after stage 10. Pay to win.
It a bug that when we enter the game it say we disconcet but our wifi still on pls fix because we love the game so much ;-;.
Great game. 4 star because we wish yall had a dark mode version so youre game isnt so bright and white. Oh and uh… Co-op a lil wild tho.
Everything seems to be completely unfair besides solo mode, specifically co-op and pvp sends us boss after boss to distract our troops and as Im looking at the enemies area they get one boss for every 3-5 of our bosses. Thats just simply stupid, no other way to put it. Its a decent game but the simple fact of it is if you dont pay money you wont win. We hope the difference is they bought the pass because they all had full teams of rare or higher troops, so we wouldn't be surprised if thats what is going on. We truly hope for the people who really enjoy the game they can just buy the pass and theyll be fine, but we will not be buying anything, in fact Im deleting the app.
The game is good but needs improvement.its impossible to level up your animals. If we win a pvp give us a chest with a timer. Just like clash Royale. Thats our only suggestion.
Absolutely love the idea and gameplay of the game, but the fact that you legitimelty can't grind into oblivion to get more animals / coins is an instant 1 star from us since you can only replay levels a few times a day. Nope. Uninstalled.
Fun game, with plenty of customization and interesting gameplay the only thing that throws us off a bit is how punishing co-op seems compared to the two other modes. Especially when youre paired with what seems to be almost entirely bots; its incredibly hard to get to wave 10, let alone past that. Could use a bit more information on bosses/enemy types too didnt realize one could take away units until we had seen it several times.
Its a very interesting game, unique in its own right, really reminds us of our childhood flash games.
We have spent zero $$ on this game, and have never felt the need to anyways. We just hate how if we go afk during co-op, we still get wayyy more kills than partner wayyyyy too consistently. May we suggest maybe some sort of in game chat server, with a function to play co-op with people you chat with in game? You could also easily make that function work for challenging people to pvp too. We just feel like that implementation of human interaction, for those that BOTH have complaints like ours, or just plain want this function anyways, would make the game more appealing to a lot of people.
The core gameplay is fun, very RNG dependent but with the right team of defense towers you can progress and learn. However the Gatcha system is our main complaint… It seems to not only return the desired tower cards used in upgrading your towers/gaining new ones. But also the very currency you spend to open said gatcha at a extremely reduced rate. If we spend 500 gold (which without bonus rewards can take a looooong time to earn) for a 3 pull gatcha instead of getting 3 tower cards you are likely to get mayyyybe 1 new tower card and 2 cards of less than 50 gold (combined) back. Same goes for the token boxes. This feels like a ripoff mechanic and devalues the gatcha system quite a bit. The gem pull works the same way. You are better off just saving your gold and gems and buying directly from the shop. Plz remove currency from the gatcha system… We can earn that naturally.
Fun for awhile, doesnt take long to hit pay wall. Money earned completing a level is so low! Even when we have enough money to upgrade a character, it tells us we dont have enough animals.. What does that mean? What are summoning stones? Should we invest in them if we dont know what they do? We are on level 32. Sometimes we play an earlier level just to grind-today we couldnt beat levels 29, 30 even though we beat them yesterday no problem. We think this could be really fun.
Fun game for a little but around level 35-40 progression absolutely halts. Cool concept but very poor execution.
The newest update took the one thing everyone already complained about (the lack of ability to progress) and made it even worse to the point that Im uninstalling.
A refreshing twist to tower defense! Lots of adorable animals and wizards to collect and experiment. Simple gameplay with deep strategy and many fun levels.
An update to co-op for more fun has completely ruined any progression. It is so difficult that our team of leveled up legendaries can barely last past wave 10. The reward averages 5 coins which is abysmal compared to the cost of upgrades and shop items. Subsequent updates to balance gameplay progression has changed nothing. Each wave has monsters with HP that sky rocket. Summoning is too expensive to deal with the increased amount of high Hp monsters and you cant kill enough to upgrade damage during co-op gameplay. Until the co-op is fixed, we cant find ourselves investing in this game. We have no interest in pvp as we play this with friends. We wont be recommending this game now because of the nearly impossible to play co-op. No more fun. We suggest lowering the monster/boss HP in co-op, increasing the rewards, or increasing the amount of points gained when defeating them.
Seems neat. While it is, clear and obvious pay wall after a few matches. Hate developers like this.
