Great puzzle game. Maybe it's just me, but it's surprisingly difficult and complex. Other than early on, you can't brute force puzzles, which is nice. Lots of strategies and mechanics can be used to help figure out the solution. Very good, and proper, puzzle experience.

A well executed puzzle game that uses a handful of simple mechanics to produce impressively complex challenges. The difficulty ramp feels just right, and even better, you aren't required to solve each puzzle before unlocking the next. Solid graphics, acceptable controls. A little variety in music would have been nice, but at least the audio settings let you mute it.

A great puzzle game that kept me entertained (and sometimes scratching my head!) for hours.
