Use [Space] to fire the gun and press the [R] key to reload
Credit to @KscratcherJ for the initial sprites (apart from the ammo counter). I know he originally created the project, but I deleted every single block of code and therefore none of the scripting is by him. Like I said I also added a new sprite and something I didn't mention, sounds. Go check out his version anyway because I wouldn't have made this if he/she hadn't given me the idea :)
