Hey this is very similar to the game I entered in to the jam! They both have mages that all they can do is move and aim while random potions/spells are used against a horde of enemies! I will say though your game has far better graphics :)

I liked it. Looked nice and very cool concept about how the attacks go along with the beat. Only couple comments I have are:

• The graphics are nice but after about 30 seconds each game the framerate would drop quite a bit on my laptop. I'm sure not a problem with those with better systems, but made it a little tougher for me.
• Maybe a little more leniency or heads up would be nice. Everytime I ran in that hall in the top left area a goblin would come from the opposite direction and pretty much insta-kill me. Makes me think the only safe areas are the dance floors. Maybe if they had more of an attack animation that had to play first, or the camera was zoomed out or a directional arrow would help in those cases.

Anyway very nicely done though! Really great theme and idea! 

I really wanted to play this one, but I had trouble getting it to run on my laptop. Frame rate kept dropping pretty low.
