This Platformer focuses entirely upon exploration and puzzle solving.  Imagine Yume Nikk, but with more focus, less dead space, less beauty, and less surrealism.  That's not to say that it isn't beautiful or surreal, though; you'll travel through a wide variety of lovely areas throughout this world.  Some of the puzzles are infuriating, but most are pretty reasonable, and you'll actually have to think about them; some even have really interesting moments that teach you secret mechanics without saying a word.
