Community Insight:

Im hoping to see Ratopia on iOS soon.


When we try to load a match to start the game it automatically crashes in loading screen.


Love the game and this style is so unique its hard to find. Many games are copies but this game build is unique love it. Unlocked everything for achievements and two leaders but unable to purchase any more we want to throw money at this game please.


Wonderful game! Our only wish is that there were more cards. It runs great and each classs gameplay is significantly different.


Im assuming this game was created by a small team of developers. You made a truly unique, gem of a game. It does crash about every one in 10 play throughs, always right before a large wave of enemies. But since this looks like a small company, and can be fixed, Im still giving it 5 stars. Take a chance and play this game.


The game is just one of the best mobile ones Ive seen, great quality in art and gameplay, wish we could unlock the other leaders without paying but that doesnt subtract from our experience. This game is high quality and worth the 5 star. If it appears difficult just keep trying its taken us numerous tries to win. And the 1 star reviews are from idiots who dont read the system requirements so please dont be stupid. Great game stupid reviews.


We're an artist who has been working on a game idea for many years now.. We're actually turning it into a comic because we're not a game maker we're more of an artist but it has mice rats and cats in its in it and this art was very inspiring. Really great work. Wish we could work for these guys.


The game is overall fun and it is clear lots of work was put in. If you read all the one star reveiws, they say the game crashes all the time, THIS IS ONLY FOR SOME PHONES. We dont think its fair to rate this game 1 star just because the phone cant handle it. Game is fun, stop rating 1 star because of crashes, it works perfectly fine for us.


After trying it out we bought all the leaders and we really love it. Each leader has a very unique feel from one another and the different zones give some diversity as well. (The navigator leader seems in need of a buff, but we may just be missing something) One pretty major gripe we have is that theres a crashing issue when we try to continue into endless mode after technically beating a run. Its not consistent on exactly when it happens, but it always happens fairly soon after. Whats more is that it often also removes our save so we cant even get back in and continue. All in all though we really love the game and Im looking foreword to any future updates that come. Keep up the great work and dont let the bad reviews from people playing on decade old phones complaining about crashes get you down.


Bugs us that so many are dogging on this game. Not due to the gameplay, but due to lack of ability to read/understand the hardware requirements for this game. Seems a majority of the 1 star reviews are due to technical/hardware issues, not with gameplay itself. All in all one of the best games Ive played on mobile. With the free leaders you can enjoy the game, no forced ads, ect. Seriously, very well done. So much so we did purchase the extra leaders. Warming, this game take time, patience, practice. It is not an easy game by any means. We believe the developers can either make this game unavailable for anyone on too old of a device. (Could be wrong though.) if thats possible Id recommend doing that.


The people who gave this game a bad review or not patient enough, or smart enough to enjoy it. This is a fantastic foray into RTS deck building! Well done.


Not sure what the bad reviews are for. This game is amazing and the first two leaders are free with no in game shop the game is challenging but fair. If you try to play on a junk phone thats on you. IPhone XR here and runs great. Only bug we have is when you upgrade the trebuchet a bunch of red text comes up as the code and gives an error but it goes away.


Nerds some QOL updates, but theres nothing wrong the game itself. We found it fun.


As someone who seems to have been fortunate enough to have the game to work without any issues we wanted share that it is quite fun and engaging as a hybrid of a few different genres/games Ive played in the past. Its challenging as well which makes it more interesting. We recommend trying it and not being dissuaded by the negative reviews, assuming you have a device new enough to get it to run without issues.


This game has given us 100s of hours of fun, But recently we had uninstalled it to try and fix a bug and when we came back in we our stuff was gone. We pressed the restore purchases button and nothing happened.


Seriously fun game. Could use a few balance tweeks here and there. The transition fom early to mid game is too easy, and the transition from mid game to late game is brutally hard in a lot of matches, but overall enjoyable game with a lot of depth. Well done.


When we first saw this game it looked pretty cool but then we start a new game and crash we try again crash this game looks really cool but it just crashes every time we try to start a new game.


Its a great game heck id even spend money to play more but it just doesnt get any updates making it seem abandoned and dead.


Great game but wont let us buy leaders anymore.


Ive been waiting to play this game and when we try to load the game it just says loading and exits to our Home Screen. Please fix this. Im on iPad btw.


We really enjoy this game, our family does as well. We would give it 5 starts if the following was fixed/updated. The game needs support for: – Cloud save to keep our unlock progress across devices – Family sharing for unlocked/purchased characters Bugs: – Restore purchases does not function.


The game looks overall amazing and good looking but we havent Even played it and it crashes any tips or fixes that could prevent it.


There's only sound, and it's always white.


What is available is fun. Played a year ago and bought one of the leaders. The game got deleted and reinstalled. The bought leader is no longer available. Fine, Ill buy it again and some other leaders. It will not let us buy any. Where the buy button should be, it is blank. Can only play the 2 free leaders. Already checked our account settings to allow in-app purchases. Wouldnt recommend this game unless you are happy with only having 2 leaders.


Game crashes when we try to load into any settlement and we havent even played the tutorial yet. There are also only 2 free leaders the rest are locked behind a pay wall which is not advertised well. We get you have to make money but dont say theres more to the game than there is.


There is no option to unlock heroes for us. Im on an iPhone 13 pro max. We tried deleting the game and reinstalling, but there still isnt an option to unlock heroes AND we lost all our progress with the first 2. We were more than willing to give money to unlock the shaman, but not now.


We would be more than happy to give it 5 stars only if the game worked Ive tried everything but we sorry to say it but we wont play a game that we cant play LITERALLY mainly because EVERY time we TRY to make a new settle menu even with or without tutorial we crashes during the loading screen and Im tired of it so until further notice we gonna uninstall the game sorry we hope you fix this soon cause its a game we would really enjoy.


At the type of typing this up the game crashes when we try to start playing the game.


App crash we click star button (in-game).


Anytime we try to open the game up and start a match it starts loading but it then closes out and Ive tried multiple times to get it to work but its still not running.


So, we see this cool looking game on the appstore, so we download it. We see he different leader options upon opening the game, so we decide to buy the shaman because hey why dont we treat ourselves? We pick the land we want to start in, and it loads for 5 seconds before crashing, rinse and repeat 7 times, this game took our money and we cant even play it, piece of garbage.


We deleted this game and it keeps downloading itself back on our iPhone. Its pretty frustrating to see this game back phone.


Ive looked at the other reviews to see if anyone else has this problem and before the devs say you need more than 3gb we have much more than 3gb of storage available on our phone so we dont know what to do. Really disappointing because it looks like a fun game.


PC version is super fun. For people that have never played it, add deck building to kingdom new lands/two crowns and thats what this game is. Really fun, hopefully they can fix the 3g ram issue, cause Im on iPhone 8 and it crashes at start but we will patiently wait for a fix.


We like how you mixed the idea of those card games like StS and Kingdom. Also the rats are cute.


We have played a lot of mobile deck builders and this is the first time we have left a review. We have only scratched the surface of what this game has to offer but the complexity within is already self evident. This is incredibly well published and we were shocked to see only one rating on it at the time of download. Definitely one of the best deck builders we have seen, let alone mobile deck builder.


Game is overall fun, however our main complaint is the tedium of managing where your units go. If you have say, 20 units on a single wall, then the coming wave has enemies coming from both directions, you have to individually select each unit to send to the other side instead of a way to send half. We think some sort of unit management screen would really help playability in this aspect.


The gameplay is great but the resolution is stretched on our ipad such that all images are distorted.


Game keeps crashing on our ipad, right after we try to start the first scenario with the tutorial.


This game looks so good Im on an iPhone 8 and up to date on iOS but it crashes and closes on the loading screen when starting a new game , so we cant play. Please look into a fix for this.


Nice game but unfortunately the game is crashing while Im playing it. Im using ipad air 3rd generation, ipados 15.


Game does not load, dont waste your time.


We did our research on the game trying not to spoil too much and the game looks like some thing we could play for hours. However the game does not work for an iPhone 8. If there was a way to run the game on our phone we would happily change the review to a 5 Star. In our opinion we guess it makes sense that the game should run on the newer phones but we should not be able to download the game at all if it can't run on our phone. We've seen other games that won't install on our phone because they weren't built for our phone. We saw it a lot more back when we owned a iPhone 6. Until then we will happily wait for an update to fix the game for older phone user. Even if the game doesn't look as pretty as it does on the newer phones we believe we should still be able to at least play the game.


Wont even let you play. After selecting where to start it instantly crashes.


It wouldnt work on iOS 14, we updated to iOS 15 and still wont work. We get to choose our character and level but when loading it crashes out. We have a 6th gen iPad. It says its compatible.


Game crashes on the loading screen. IPhone 10 running iOS 14 then upgraded to iOS 15, no difference.
