Pretty fun game. I noticed a bug with the movement though, if you keep going in one direction while shooting your character keeps slowing done till they completely stop, once you stop it resets and you can move again. Feels like its a recoil effect that's stacking against your movement speed. Also, you might wanna add a slight pause of some kind before the end boss, the instant I touched the door I was in the middle of the boss hitting me and died almost instantly upon entering the room. other that that it was really fun, I liked flying around and shooting.
