A highly recommended game that's a one of the most creative and original I've seen. A cross between an interactive story and a Mario Galaxy-style physics puzzler, the game is incredibly fun to play. It's simple & colorful pencil & paper -style graphics work remarkably well for this story, and its music is gorgeous. While the game is short and many will finish it within a few hours of play, it's such an enjoyable experience it should be very replayable.
One aspect of the game that's really cool is that while each level/screen has a specific task that requires flying around, it's so much fun to fly the character around that I'll often just spent time looping through the air without concern for whether the task is completed or not.
This is one of the best games I've bought in years.
The game can be bought from GravityGhost.com or on Steam, though the direct link is a better deal.
