I think the game's concept is pretty cool, I found it enjoyable!
one of the main issues is its super easy to cheese? like I can just stand in the corner and spam bullets and win, with how reloading works too I don't need to worry, and enemies just run into the bullets, I think it'd be cool to have more variety in enemies, like one that flies, needing a specific weapon, or ones that have a chance to dodge!
I hope you expand on this, cause I can see this being a real fun game :D
