Sound design, music, and the arena are all really cool. Aiming felt a bit weird, since it didn't seem like I was aiming right where the camera was pointing, and I often couldn't see enemies through the character's body, so I ended up missing a lot, which, of course, resulted in me needed to fly around for a bit while I waited to regain power. There are a lot of great ideas here, so I hope you keep at it!
