The game server is still around but its hard to find any time to move it forward. The game is actually much larger than I remembered and it was taking a long time to convert everything and make it "safe" for multiple players at once. In the end I focused a bit on trying to make the old game more playable on modern servers, but even that is a bit daunting.
I'm currently working towards putting the original game back up where you can play using just a modern browser. It's kind of funny that it took this long for browsers to catch up to what we had implicitly in the modem days.
