Simple, yet effective, always had a soft spot for these sorts of games where you just end up amassing an army of pure destruction. My main issues come from the fact that the camera moves a bit too fast when moving the cursor around and can get extremely disorienting at times, and also that the difficulty ramping is a bit slow, where I felt like I could really only die if I started trying to be aggressive, rather than feeling a constant threat from the enemies. Even so, I liked this a lot, and it fit the theme excellently, great job with this :)
If you have the time I would also really appreciate if you checked out my game as well.
