OK I see what you were trying to do, but it can be improved a lot, here is some things you could change to make the game better: add a crosshair, it will really help with aim, and for it to be a bit easier to find the gun since I've done some runs and in most I couldn't find the gun, make it clear where the enemy is since it's kinda hard to spot him when he shoots you first, also if you make the itch page have screen shots from the game it'll help people acsualy understand what they're getting into since I didn't understand what was the game about or how it looked until I opened the game.
I hope I could help with this feedback.
