Gameplay 4/5 - Very smooth gameplay with a nice variety of enemies. The big bouncing boss was a lot of fun to fight. One possible to way to expand it even more would be more powerups, or make them appear more often.
Creativity 2/5 - Feels like a pretty typical rogue-like.
Art Style 3/5 - The enemies looked cool with a good balance of similarity and differing details. The constellation power-ups looked good too.
Audio 4/5 - The music was nice and energetic to match the gameplay, and the shooting sound didn't get too old over time.
Theme 4/5 - It's got plenty of stars.
