User Reviews
I love this game🤗 But.. 🤔The only problem is that 9/10 times there's the option to watch ads (Basically anywhere you see that you can watch ads!) the ads won't load so when it comes back to the game you'll be stuck on a black screen with the game music still playing in the background... All you can do now is close the game and reopen it...😮💨 And you can only re-enter the dungeon you were just playing once! So if you get the black screen twice then you'll need to restart the whole dungeon❗
I actually like the game, but the ads that never end are beyond frustrating. not all ads do it, but occasionally I get stuck in an ad I chose to watch for a reward, but after MINUTES I'm not given the multiple "x" icons needed to exit the ad back to the game to get the reward. reboot app, lose effort and time, no reward. fix this. so far it's mostly been monopoly go ads.
Fun survivor game with a lot of build strategy and enemy variation. Two things that are core to every game in this genre that makes it fun imo
cool game easy to play i like to play it at work when i don't have anything to do really fun game i hope you devs keep working on it to make it a lot better and add a lot more fun game modes and also i hope you guys don't get greedy abd make it ptw or fill it with ads cuz i like it now
