Space to start and stop, controls for more controls. Sometimes you have to press e twice. Have fun and good luck solving! Scramble sometimes undoes itself and also has weird scrambles like F2 F', which is just F3 which could just be F.
Thanks to @skinnydudes for original project and scramble system. (He's gone now) High Chance the scramble cancels itself out sometimes, just ignore it cause I'm too lazy to fix it. (Update: Really high Chance)
