Thank you It's my first game jam that I tried :) .Also game shows you when you can shoot and when yoy can't
1. When you get attacked by the enemy a bar appear and shows you how much time you need to wait before being able to shoot again.
2. When you change weapons it shows you a bar on the bottom that inducates how much time is left before finishing reloading
And Yes deleted files effect the game. Speed slows you down, gun lock makes you wait more when demaged by enemies and swap speed makes you wait more before reloading your weapon.
