Yes I know that thumbnail isn't what being colourblind looks like normally, please don't get angry at me. I've added symbols on the coloured blocks to make it more obvious for anyone who might be colorblind.
Normal ground: you can stand on it no matter what Blue ground w/ square or orange ground w/ circle: turns on or off based on the switches Purple square: dangerous, don't touch it Green ground w/ up arrow: bouncy Red ground w/ down arrow: can't jump while on it Blue circle w/ square or orange circle w/ circle inside: turns on corresponding blocks, turns off other type You start at the grey circle and try to get to the black one. Of course, big thanks to Relfirm for the original project!
