"This is a hardcore puzzle game. At some point you'll need scratch paper to plan out solutions. If spending hours figuring out exactly what 100+ series of actions will get the results you want, then pass. I loved it. The puzzles are the star, graphics are simple, story is fun but mostly MacGuffin. Has a built in “post solution to youtube” which is great because there are near infinite ways to solve puzzles and seeing what others came up with provides insight into your own thought process."
