Customer Reviews

It's my favorite app, just needs a bug fix

It's challenging and lovely. My only complaint is that on the iPhone 7 I cannot pause my game. If I get stuck on a level I can't start over, I have to delete and re-download the app. Totally worth it though.

Super glad to see this game on IOS

Loved playing this on my pc in college. A fun tower defense with great theme. I'd buy the soundtrack if they let me :/

Hey devs, any chance you can restore purchases made on a windows device ? I'll prove I bought in to it by telling you going full rockets is OP

Stupid hard

Can't get pass level 3 even tried writing down different types of setups I have used, fixing and trying something different... Still no luck.
