Moved to a different section because I'm anal about the Custom Maps section being solely for custom maps files.
As for the game, I'm trying to provide tools for custom map makers to want to map in the first place (elevators, other moving platforms, etc). I am also the "author" (though I will say that I didn't do much at all...) of many of the Demo maps as opposed to the Beta 1.1 maps, and I currently only have a project going on with Seniormeatbox mapping-wise. In most other aspects though, I just program.
If you're talking about having Beta maps, good luck. Most of the map files were lost due to Sendspace changing their policy and deleting files after a certain time period. Likewise, I only know one map maker for Beta currently...all others just moved on to the Demo.
