Love the choice of music, and the fact that the baby bops his head along to it :) I like the tutorial messages, and found the fart boost mechanic to be fun - would like to see it used in more difficult platforming sections, maybe with collectibles to hit in mid-air that would refill your boost and require another mid-air fart.
My only real complaint is the control scheme - maybe move some of the actions to the other hand? However, being able to drink / smoke / stroke a cat while playing is quite nice ;)
