I'm too cheap and lazy to put it on one of my personal servers, since I'll almost certainly lose money out of it, once I clean the gamemode up, and make it 'server admin friendly', I'll probably release it, personally, It's probably best played alone, since the levels were designed with only one player in mind, once people start making lots of levels, that may shift though.
It's also really easy to make custom blocks :D
Nice to hear that!
Once i see a release of this, i will make lots, LOTS of maps.
Also, theres the PointSample VTF flag, it makes the things look less smooth, it may help to achieve a old texture look.
