This a brilliant concept for a game. The switch between human and spirit game play adds a new dimension to the game. The art design for both the human and spirit worlds are amazing the game play is mostly solid, with one exception. Numerous times when transitioning between human and spirit midair, the two would glitch into the walls and through the floors, which lead to me falling endlessly. Also the ran very poorly for me, but that could have just been my computer. With the exception of the one bug, its a great game.
