Cool shooter !
I like the fact that you have mouse aiming in this, and the themed magic wand cursor to go with it XD
The overall spritework is really awesome be it the backgrounds, main character or the enemy roster with quite some variety to boot :O
My only tiny nitpick is the enemy arrows, they are a bit hard to see, i think instead of realistic arrows you should go for a bit flashier colorful stylized ones to help read the patterns better.
Other than that i had a good time, Good job :)
