I Win!
I had a lot of fun! The game looks and sounds great, it controls well and the need to look at the top of the screen, and to find the safe moments to do it as you're not in a rush, is a fun twist. Each fight is at least a bit different from each other, the difficulty is perfect (the game is not easy, but then it's satisfying to eventually beat it).
The fights could probably be slightly shorter. Also I think there's no feedback when damaging a boss., which made me wonder if there could be an invincibility frame, or if hitting it with more than one bullet at once did anything. The hitbox of the fog of insects (or of the player character) might be bigger than the actual sprite (but maybe not ;) ).
Thanks for sharing!
