I love the fez-ness this is so mindblowing! Sometimes I would stop and just WASD a bunch to admire the level design and cool 3D map! And not only is this a super cool idea but all the animations and effects make this so so polished and fun to play. Small things, but I love the overshoot when you go between tiles and the dither fade! They are super clean and polished. The undo mechanic is super cool too, well-done on that! And really fun brain-tickling puzzles!
