Thanks for the clarification! I hacked TRS-80 Model I hardware (for a friend), but I never cared much for TRSDOS or Lifeboat so I have missed out on that software experience. I guess this was a port of the classic Adventure game to Tandy. I had the CP/M version (550 point Colossal Cave Adventure). I had played it even earlier on RT-11 where it took about half an hour to load from two 8" floppies.
