I like all the bullet types and how they have uses and synergy but sadly that doesn't really come up in the actual game. When you shoot an enemy their number randomizes which then randomizes your bullet, which makes trying to plan or make special use of the bullet types not possible and also makes the reload action unnecessary because you can just randomize your gun way faster and deal more damage by just shooting enemies since you have a crazy rate of fire.
In terms of FPS mechanics it feels really great tbh, which is very impressive for 48 hours. It was enjoyable to play even with the crazy lag from the WebGL version. Nicely Done! <3
