Since Deuce added Atari ST/VT52 support to SyncTerm, I've been revisiting several ST BBS door games. I was particularly taken by DDST (as in "D&D").
It's a pretty good adventure game and it uses VT52 colors effectively, particularly a screen-flashing effect. It can be frustrating, but you *can* make progress, and it has good features you don't often see in door games (like "Save"!).
Well, this morning I finally beat it!
