That was a bug. But I left it in because I thought it was funny! I was going to make it a game-play element (gotta use a roadrunner to get over a hazard) but I'd need to have made some pathing for the roadrunner and just didn't have time to implement.
I apologize in advance for hijacking this comment but you are a very hard man to contact. I've actually been trying to contact you for 12 years to hire you for a project. I also have some news for you about the flash engine. I would would greatly appreciate a response.
