I love Diablo, this is a really fun reinterpretation. I never really played mage so I don't really know what the R move is doing, it doesn't seem to hurt the enemies. Also not quite sure how to beat the boss all my attacks don't seem to do any damage. Making the shot be a bit larger and stronger might help because most of the game ends up having to kite mobs as I slowly heal back. Overall great work! Keep it up!
