i like it. good mix of ideas from several well-travelled subgenres. there are no forced ads, tho the hypermonetized menus and pop-ups trying to sell you stuff can be annoying. i like the tech tree. graphics are decent for what it is. music feels good.

gone from 5 stars to 2, nerfed secondary damage, field damage and other game mechanics and not for the better, major impact to. gameplay and enjoyment. also not documented in what's new: just "bugs". NO please either explain why changes were needed or revert to previous.

I've been enjoying the game. The creator really needs to figure out how to reduce the demand from the phone's hardware in the later phases. My relatively new Android gets extraordinarily hot, and I'll have to stop playing if there's no improvement.
