It has a nice story, but black rectangles on war with white rectangles seems kinda racist. Other than that, the story is marvelous.
Edit: The quote above was from an underage 11 year old who has absolutely no idea what the hell he's saying. This game is still pretty alright, the guy moves a bit slow for me but I'm sure there are people who can appreciate slow movement. The contrast between light and dark is used well in conjunction with the game's minimalist art style. The puzzles are a bit tricky but that's a good thing because it provides challenge.
