This is an excellent puzzle game. It's very challenging at times but it's also very well paced. In the 17 worlds (with plenty of levels in each) a new mechanic is introduced, or a few of the older ones are combined so it's tough to get tired of the same old puzzles, because there's always something new to try. The soft, colorful visuals and the ambient music make it pretty relaxing too, if you just want to fiddle around a bit.

I've honestly never fallen in love with a game quite so quickly, especially having never heard anything about it before it was gifted to me one year. As a player, you're afforded so many opportunities for those wonderful "aha!" moments. So many chances to think hard inside (and outside) the game and its logic to figure out the best way to use the varied mechanics in solving puzzles in occasionally surprising ways. The level of ingenuity and creativity offered here instantly skyrocketed this unknown, oddly titled gem, to my number one favorite game of all time.
