I like the stylized graphics, the music is great and the idea is pretty unique. Also the temporary bonus mechanic is well done. Though there's something I can suggest to improve the game:
- When not controlled, the player drifts away infinitely with constant speed. I guess it's realistic but very inconvenient. I think it would be better if the player's speed was slowly decreasing when not controlled.
- The controls are very inconvenient. You have 2 actions: moving and shooting and they're way too close to each other when playing on mouse and keyboard. The 2 sets of controls should be as far away from each other as possible, e.g. WASD for movement and LMB for shooting, or arrows for movement and a key on the left side for shooting. Or just give several options.
