FREAKIN' AWESOME! I've been waiting for this!
Some things I noticed, and some suggestions.
Fancy Pants Man's hair dissapears during his climbing up from a ledge animation, then re-appears.
1: Give us the option to change FP man's hair colour as well as his fancy pants. (Assuming you bring back the option to change the color of the Fancy Pants).
2: When FP Man does a slid on Oil, maybe make the oil ignite and burn in his wake, killing enemies and FP Man alike.
3: Whenever I play this game, I always find myself thinking that some cheesy cartoon announcer kind of voice should be yelling out "Fancy Pants Man!" as if coming from a great distance, whenever FP Man does something extraordinary.
