After the first two levels, I was worried the mechanics here were overly simplistic, but having multiple levels with bridges created more possibilities, and the mechanic of being able to create a bridge by stamping a gap added a lot more depth to the game -- however, I do think that concept could have been introduced a bit better. Level 5 has a very clear setup for teaching the concept wordlessly -- you're on a small platform with the only real thing to do is to push the die forward and learn the mechanic -- so that setup probably should have been in level 4. But idk, maybe level 5 was initially first but you rearranged it because you thought it was a harder level. Anyway, level 6 was a pretty satisfying level that combined all the game's mechanics together!
