Zero Chance of Recovery

This was a game I wrote for IFComp 2022. It involves a famous chess endgame study.

It is a z-machine game, so any z-machine interpreter should work.

You need to work your way through three similar scenarios to win. You can "win" the third without winning the game. There is a small thing to notice that goes beyond chess.

Notes about stuff I want to fix for future releases:

1. there's a bug in some cases where if you make the wrong first move in the second and third scenarios, the game doesn't work. I haven't figured how to fix this *and* test all the remaining cases, but I want to.

2. R restarts a scenario. I forgot to put that in the verbs.

3. HDR adjusts the header, and it'd be neat to have feedback with how that works even if you get stuck with the chess.
