Meant to use turbo mode, !!! PRESS SPACE TO START THE SIM !!! There's a puzzle in an old game called Safecracker 2, one that looks like a fancier version of this, and I assumed you had to put the marble in ALL 4 holes, only moving in the cardinal directions, like an ice puzzle. Spoiler: you only have to solve it one time, with one hole. I decided to finish it cause it was a fun challenge to get branching (sorta) chains in scratch. I (stupidly) shrunk the defined 20px square grid down, which made the step size some float that I'm not gonna bother finding. sometimes the marble gets misaligned, but the T blocks should look similar so what can ya do.
