Monuments of Mars Volume 3 any% -  

Monuments of Mars Volume 3: The Fortress freeware version, DOSBox version 0.74.3 at auto (3000) cycles. Game is low-tech enough that default cycles are sufficient for play.
Start time is the first fully-rendered frame of gameplay (game tiles and character are present on screen); end time is the first frame of screen-flashing immediately preceding the "CONGRATULATIONS!" message.
Not much special on this run, just some difficult platform cycles to achieve. Level 12's death is me trying to fire and failing utterly, something that occasionally does happen from time to time. Rest of the run went quite well though, and this game is hard to WANT to run, so I'm fine with the way it turned out.
