Game flow now lists all movement-loop keys (M/joy-A minimap, S cat
sense, C cheat landing one move short of the exit), and the MSXgl
configuration section covers the full audio stack including ayFX.

### MSXgl configuration
`msxgl_config.h` is the per-project feature switch for the dynamically-compiled library:
SCREEN 5 (G4) and SCREEN 8 (G7) modes, VDP commands, 16×16 sprites, keyboard+joystick
input, and the lVGM/PSG/MSX-Music replayer (see "Music"). Enabling a library feature the
game starts using generally requires flipping the matching `*_USE_*` define here **and**
adding the module to `LibModules` in `project_config.js`.
