Prime Mover

I preferred Turing Complete, where the signals are instantaneous. There's something about the Zachtronics style "things move in lockstep" that my brain doesn't wrap around quite right. YMMV.

The best puzzle game I've played. There's a bit of a learning curve but it is extremely satisfying. Another review put it best: "It introduces merely 8 [exceedingly simple] functional components (and they are ALWAYS available - no gimmicks!)." i.e. no lazy level design where a tool is removed to increase difficulty. Building something like an indexable array or max function from just these simple tools, and watching it come to life in the games juicy art style, is so fun. If your having trouble just spam some circuit boards and I promise something will start coming together. Also try to make your designs not rely on the timing of the wires until you optimize :)

Game 176 of my backlog It is an EXCELLENT Zachlike. Explanations are solid. Mechanics are fun. Puzzles are HARD. I managed to get through the first 4 worlds pretty easily. World 5 has stumped me. Hit my quota on this one. Requires some chessmaster intellect for some of those later puzzles. Bottom line: If you love Zachlikes, pick this up.

For folks who love Zachtronics games, Prime Mover fits the bill perfectly. I found it to be a more difficult variant, and incredibly rewarding when you solve it! The highly complex components you can build with dead-simple atomic pieces is astounding. Having infinite space to work on is also a great relief, although I do wish you also had infinite time (mainly just for the final puzzles).

Very fun puzzle game, definitely makes you use your brain. Only feature I would've liked is a more in depth leaderboard.

An idiosyncratic programming game about moving and manipulating numbers. If you want to solve some very challenging engineering problems, this game is for you.
