Excellent setup pitting the player against their own avarice. Most of the levels would be no problem if I took my time with things, but trying to get to slick with my bets usually involved me losing out on all of them.
I also thought is was pretty neat how the pathways evolve from a pure platformer setup into a partial puzzle setup. The constraint on jump direction forces the player to stop and take a look or else risk skunking their run in a dead end.
