Hey! I can see good potential in your game so far, the core gameplay felt fun and responsive, although a bit unfair at times. It felt like I could never find enemies before they found me, so I'd always take a bit of chip damage in my encounters. I feel like the camera needs to be a little zoomed out so I can spot enemies in advance. The middle-mouse camera felt a little too extreme to be usable in that regard.
Another thing is when I first shot my gun I got jumpscared by the volume. I think the game would benefit from a volume setting.
One last thing, I pressed R to reload my gun, but it reloaded the level instead. That gave me a hearty chuckle, but you should still probably add that to your explanation of the controls on your page.
