A polished and clever 2D puzzle-platformer (leaning much more towards the "puzzle" end of that spectrum), with a 3D twist that mostly amounts to a presentation gimmick and doesn't impact gameplay too much - but man, what a presentation gimmick it is! A few frustrating difficulty spikes, and the final area introduces a new mechanic very different from anything the game has done up to that point that it really ought to have explained better, but definitely recommended for fans of the genre.
