My F-Zero rip-off? You know, I'm actually honored that it's still in someone's memory. I'll tell you what happened: School happened, then I got bored with it, then I decided the enormous amount of time spent on making every track so isn't worth it.
If I could somehow magically create a non-tile based level editor that still has the stability of a tile based one, I'd continue making tracks for it. No, really, I would. I actually found the old .gam file on my HD and played it just last week. It's.. much harder than I remembered...
