Just as the original, this game is really fun to play. Controls are solid for pixel perfect platform speed running, gadgets add enough new flavour to keep the gameplay from getting repetitive and the level design is some really impressive stuff. It's challenging but definitely rewarding. I would give this game five stars but sadly there are some annoying issues. The game has a nasty habit of crashing, but only when it tries loading leaderboards whilst perusing the level select interface. It also finds zero results for community levels. I don't know if these problems are solely my bad luck or if it's a common experience, but yeah it's been sucking fun out for me anyway. Overall if you like games like Braid, Limbo or other quirky and dark puzzle platformers then it's worth the price tag.
