Loved the music and simple nature of the game! I think the bullets and patterns were well done, and the whole idea of the enemies mimicing their attacks with ones you can reflect back to them.
My only critique (besides the explosion sfx when getting hit lol) is that the visual presentation isn't fully there. The background was lovely, I'll give you that. But there's no real indication that your projectiles were splitting into other projectiles so I kept getting cheap shotted by that. Also, the enemy artwork was cute, but I would have liked to see another frame or two of animation for stuff like attacking,
