I'm doing it deliberately this time, though. The handy rewind function makes it far less annoying when you impale the Prince; indeed, you can rewind and do it repeatedly.
Taking its queue from Canabalt, this Forgotten Sands flash game has the Prince auto-running from left to right. It's a little more complex than the typical one-button game. It uses three buttons!
You can hit Up to jump, Down to rewind, and Space to attack. Holding Up lets the Prince briefly run up a wall or roof run, depending on the situation. Hitting Space while jumping will see the Prince perform a ground pound attack.
It's surprisingly good, too. Just watch out for those spikes.
