Really great.
This game is incredible. It has a solid gameplay concept that complexifies over time, similar to Portal; it has an elegant plot that starts out simple and sweet and (literally) explodes in the finale. The artwork is absolutely gorgeous, with really beautiful animation accompanying it.
The game is long enough, especially for the price of $3.99, and the secret stars only add to the length. The puzzles are never repetitive, and each world incorporates a different and unique concept. This game is fantastic, and if its still on sale by the time you read this, I urge you to buy it. Id say its worth up to $15.
