-- A game description:  data, not code.  Forge/AuthorCompile.singe turns it into a Singe game.
--
-- Genre one of the two the first slice was built on.  A single world2d room, a character that runs
-- and jumps, a prize, and a readout.  It shares nothing with the QTE beside it -- no disc, no
-- branching, no time windows -- which is the point:  if the core can express both, it is not
-- secretly a platformer engine or secretly a laserdisc engine.
