I forgot to review this when I finished it several months ago, but it's maintained its shine in my memory since. One of the great puzzle games from last decade, with just the right amount of abstract weirdness and outside-the-box thinking required, which could've been infuriating instead of fascinating. I played through on a PC, but I remember it playing just as well on an iPad the first time I tinkered with it without finishing it. So, so close to being a 5-star game for me, though I can't put my finger on what it's missing.
