You did a great job with the difficulty. I died on wave 15. I also played the windows build, because I understand what web build does to a game. I think it would be nice to know how much health the enemies had, along with how much damage you were doing to them. A lot of the enemies just tanked a lot of bullets. Sometimes, the blocks you pick up gave you 0 ammo. I feel like it was intentional, but it's not a great feeling after you just got all your blocks taken away after getting hit lol. Overall, I enjoyed the game and the particles were fun to look at. The menu and settings screen is also really impressive! Best one I've seen so far.
