This game is fucking amazing. It's super replayable due to the cost-area-cycles split encouraging you to solve puzzles in the most optimal configuration for one of those choices. Most puzzles are easily beatable if you want to be inefficient in some way, so it's pretty difficult to get actually stuck, and even inefficient solutions are usually effective in one of those categories. Completing each level will give you the option to save a GIF of your machine working, which I have saved more than once because of how satisfying some solutions are to watch.

Didn't really pay much attention to the story because it's pretty intrusive. If you play this game learn how to use the hotkeys and the copy paste, since they are pretty important mechanics. Only regret about this game is that I played it instead of doing uni work too much.
