Interesting concept and pretty good art too but the UI looks a bit weird and the xp (?) orbs always scare me cuz I think its an enemy bullet ( btw u should normalize the direction vector for movement so you dont move faster diagonally )
I like the graphics but I got stuck at level 6 ( or the one with 3 white wizards guarding the orb ) in the past level I though they move when they kill me but they didnt kill me in at level 6
