I really like the idea and really really like the look and music of this.
You could make it way better if you polish it up. Like the mouse cursor is sometimes dizzy, music doesnt loop, enemies just dont see you usualy and reloding so often doesnt add tention but just gets annoying.
I know that that's a lot of negative stuff but this all there is to make this game way way better. And cuz of that, its actually not that much.
You definetly got everything it takes to make top tier games (this entry is impressive for 48 hours)
Keep making games!
