Looks great. I'm abit worried about it being free, though. People that take on arduous tasks for free tend to get tired of it after some time.

Open source helps a lot here, though, so I'm not too worried. Source is here, fwiw: https://github.com/timfraedrich/OutRun

Edit: Looks like the project is abandoned. So, yeah, maybe it should have costed a couple of bucks.
