I really enjoyed this innovative puzzle game! The mechanics are introduced slowly so that you have the perfect amount of time to learn them. I do wish I could skip one level at a time if I felt really stuck, because there have been levels where I really wanted to move on and come back later. Also, the game sometimes takes multiple clicks to register that I'm clicking on a space, which gets a bit annoying if I'm playing many levels in a row. Overall, though, this game kept my interest and was the perfect amount of challenging!
