Simple but fun, the fact that the collisions offset's were consistant was a good way to keep it fair / not require too much guessing while still feeling buggy and unfinished. Not sure what all the different platform types were supposed to do if they did work though (I think blue = horizontal movement, green = vertical movement just from the level design, not sure about the others)
Also having the debug mode show the colliders was a clever thematic way to have an easier mode.
