Dont bother with this game if you are not ready for a very stimulating mental challenge. Dennis and his brother, Mark, know how to challenge your logic and your patience. All of their games (Boxed In 1, 2, and 3, Iced In 1 and 2, and Relix) are mind exercisers without extensive how-to-play instructions. All levels are solvable...but only if you are patient and determined. Controls are fine and hasnt crashed once for me. Highly recommended, but only if you are up to the challenge.
