This game has an immense potential! The concept is just so creative and fitting to the theme!

But here maybe a few improvements:

I know the theme was "out of control" and the player controller in this game fits really well to this theme, although it really isn't as fun as with normal controls (that's just my opinion). Since you already have that with the shooting, it wouldn't be out of the theme without those controls.

Then add more feedback to the player, I want to feel that juice when I hit an enemy, you know what I mean?  It's the same thing for getting damage, at the moment I don't feel the pain!

If you simply add a little camera shake here and there the game would feel so much more alive.

But don't take me wrong, this game is awesome and I had quite fun playing it! The things I wrote above, were my only issues. Keep up the great work!

Also, pls feel free to check out my game as well :D

Lots of potential. I don't like the feel of the controls, and think wasd should make the player move in relation to the screen, not in relation to the way the character faces (at first I thought these awkward controls were a punishment for shooting for too long). The audio was bugging out for me, and there didn't seem to be any boundaries to the levels. The controls were too uncomfortable to use to get very far. Nice visuals and music (when it wasn't glitching).

Haha I like that you can get lost in the dark. Setting up the controls to be relative to the direction you are facing was interesting for the game premise. 

I really liked the mood of the game. Some things you could add to make it "feel" better:

1-Screen shake

2-Particles

3-And a flashing effect when the enemies take damage

(Also in the end it shouldn't be "shoot to quit", but "shoot to restart".)

Good luck!
