I double-checked and I'm honestly surprised that a ZZT edition does not exist :) Part of it might have been that it was a team-based game, but this GZDoom remake reworked it very nicely. Thinking about the mechanics if a ZZT version were to follow that same kind of pattern, the near-useless "Re-enter when zapped" board flag could be used to enforce the time limit, transporting the player out of the game behind a locked door near the entrance and forcing them to exit the board via a passage leading to the prison area instead. With that done, the challenges really could be anything already achievable in ZZT.
