My wife just finished this game last night. She usually sticks to the usual boring flash games, but got into this and was up late finishing it. It was about 8 hours of play for her (with the usual web browsing and such). She really enjoyed it. I don't think it has much replay value (yet). The difficulty definitely ramped up in the last 12 levels. We really enjoyed the gameplay. To break it down further it combines a 2d-portal element, side scroll elements and puzzle elements in a cohesive way.
