I think you could imrpove on the audio ( add some gun shot effects) Add a scroll wheel for different weapons, I would also improve the quality of the floor because right now it makes you fall in a little bit so fix the y axis. But over decent game just improve the sound and game quality make it 4k or 1440p overall rating 3 stars (Developer*) 4.1 Stars for (*Playing)* You could definetly turn this into a real great game! Just fix the floor bug and audio
