Really fun game. I have a few suggestions tho:
- Reduce camera shake a little
- Feedback (visual and audio) when you are shooting an enemy. Like either, they flash a tint of white, or blood splatter, or both.
- Increase health of both the player and enemies (or increase health of player and have more enemies), and have health regenerate. I think this one is especially important because when playing the game, it feels so fun to just rush in gun ho and shoot the enemies down, but because of my low health, I have to play it slow which I feel contradicts the feeling that you want.
- Reduce the radius of the light cone when shooting. It seems as though the light cone is where the bullets are spreading, but apparently not.
Overall, a really fun game. Great work!
