Ratings and reviews

It's a really good game and would be 5 stars but recently it hasent been loading at all, it just stays on the loading screen. I don't know what problem is, I've tried it online and offline either way it dosen't work. It's a really good game and I don't want to have to uninstall it, especially because I've spent several hours playing the game. So I really hope that the devs fix this issue

Excellent game. As a PC gamer, I will play it even when I have PC games available. Good game play loop. Multiple strategies are viable. Lots of options to play with. Only complaint is in offline mode (which can still access Internet strangely), even if you pay for the upgrade, the only way to use other overlords is to watch ads since there is no currency in offline mode (hourglasses). As someone who plays this game offline, with no Internet access. This would be a nice change to have.

This is really fun to play, it's got a lot of cool odds and ends to mess with. All the monster races all feel very unique and are all powerful if you equip them right. Once you complete a run ,you'll get progress to unlock cards that will boost a certain aspect of your next run, so even if you keep losing, you're still becoming stronger for the next run. And as long as you play online, there are no forced ads to annoy anyone. Plus, the tutorial is very helpful to explain the basics of the game.
