Holy heck this game is freaking hard! I LOVE the way the characters bob to the beat of the music (which is equally awesome). The mechanics I think would be super fun but the area you have to play in is just too darn tight for me to be able to survive for long enough to get anywhere. I tried about 10 times and got to about the 4th change in moveset on my best one. I don't know if there's an ending to it or not, but sadly I'm not sure I'll ever be skilled enough to see it. I'm not sure if you updated the difficulty or not on the MAC build, but I played it on Windows. Great game though!
