It's a whore trust me... I've put 90min into it and only have so far been able to finish the Galaxy Man stage (the easiest.)
The problem is that anything 'normal' about the shared designs of previous games are gone. Waypoint drops those 'S' shaped rooms can kill you with spikes at the bottom. Cheap things can drop in instantly with no clue and toss your ass into spikes/pits. They've added in ton of 1hit death things on ugly jumps and other areas so you need to be perfect or damn near it. The game basically was made as both a test of patience, but as something only the most played out and die hard still up to date MM fan can put up with. Most people I know want their $10 back or will just rarely pick at it(I'm in that group.) The game is just overkill.
