Monuments of Mars Volume 1 any% -

Monuments of Mars Volume 1: First Contact 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.
This game is hard to play: lots of falling through thin platforms, dying to enemies you aren't that close to, and inputs that don't happen. But there are times this can be exploited for the benefit of the run, such as the "robot jump" in level 8, so it balances out a little. The death in level 13 can be avoided but I missed the jump on the first try.
There are definitely ways to improve this, possibly to the point of a sub-9 run, but level 20 in particular is very dangerous to improve past what I have here. I'd call this the weakest of my runs across the four volumes, but it's also the most boring so I'm not all that keen to make it better, either.
