An excellent puzzle game that has fairly simple mechanics but uses those mechanics to the fullest, resulting in some fairly difficult puzzles. Do note that simple mechanics are a good thing--some puzzle games suffer from being overly complicated, at which point you're not so much trying to solve the puzzle but moreso trying to understand the mechanics of the game.The solutions themselves are not tedious to execute (most solutions take under 30 seconds to execute), but may take quite a while to find (there are puzzles that have taken me over half an hour). The UI is also simple and intuitive. All-in-all, a great puzzle game. Give it a try!
