Funny game.
Found a small optimization where you can cover slightly more per jump if you crouch around the end of a jump, saves a smidge each time, other than that, its all standard.
Anyway, there's a lot of RNG in this game, having to get the speed boost as soon as possible in every level, plus either the fireball or the thunder powerups to deal with enemies faster while not losing health, or at least not as much.
Some frames are lost before starting the game to get good RNG and get the fireball and the gauntlets at the start.
The world version is used for the faster start screen btw.
