I feel justified yet disgusted with myself at the same time
Which one? TSAT, Doom EU, or Koliko's Adventure?
IIRC, he handed it off to someone else, and it's more or less in active development if the project thread can be trusted.
If the former, I'm actually back on the project (PDF has a tendency to over-react, makes it a pain in the ass to work with him sometimes). To be honest, I'm the only one doing any work on the game, PDF himself on Sonic Retro's thread about the project that I've done more on the game in the six months that I've been on than he's done in the last two years (exactly my opinion on the matter as well, before he even said that).
If you meant the second, I did hand it off to him, but I restarted it in my own version (the one you can find here). We've been going our own ways with it, my version is attempting to be very faithful to the alphas, whereas he's developing it with more of a base on the Doom Bible. Both are active (his is probably more active than mine, at the moment)
If you meant the latter, it's still in development, but I haven't done anything on it since I've been losered, since I couldn't communicate with any of my mappers. (by the way, guys, PM me if you have anything important to tell me since then, if you're reading this, you obviously realize I'm back)
