Two excellent, claustrophobic, labyrinthine maps set in tight spaces.
It's fun to find the secrets.
I've played both maps twice, and I still can't get enough of them.
No complaints, just a suggestion:
I would have liked to have had a teleporter back in the exit room of lpqsp3b. Or did I just not find it?
Are we going to get a whole episode?
I simply forgot to include a teleport back from the boss fight. I guess players will just have to noclip back to explore more (the room is pretty close to the start, anyway).
As for your second question, at this point I am more interested in other projects (a Doom WAD, original games, maybe a Thief FM if the PyTaffers' editor gets released), but I won't rule out returning to Quake in the future!
