Possibly my least favorite Zachtronic puzzle game so far. It has all the claustrophobic space constraints of Spacechem without any of the visual excitement. The commitment to the bit, while laudable, really hampers to UI and debuggability of the game. While of course the programming language needs to be constrained to actually allow for puzzles, it (much more than, say, Exapunks) makes anything even moderately complex feel like a slog. By the time I got to the end, I no longer had it in me to put effort into optimization on any axis, which is a bit of a shame because when I'm in the flow I really do love coming up with galaxy brain solutions to these things.
