Genuinely masterful. A puzzle game for the truly obsessive puzzle solvers out there. It expects a lot from you, but the puzzles are consistently fair, challenging, and incredibly satisfying to solve. If you're not willing to spend multiple hours on individual one-screen puzzles, you're going to have a bad time. But, if you're like me and can't get enough complex problem solving in your games, then you're going to fall in love with this. I cannot recommend this game enough, and I really wish more people knew about it. It's frankly tragic how unknown it still is over five years after it's release.
