Was able to play on Mac. I LOVE the level select dice, the animation on those was really nice. When they first dropped down it was pretty mysterious - didn't know what I was in for. Having said that, it be better IMO if you only watched them drop once, rather than every time you finish a level.
I got completely stuck on level 5 & there were some weird graphical glitches at times with what I presume were moving enemies, but the Sound Effects and general ideas of the game were sound :)
