OnceSet

In depth

One key holding a set rather than a key per flag, because a game accumulates dozens of these and a key each turns a player's save into a junk drawer that cannot be cleared in one action.

Where it persists is the store's problem. When the store cannot keep anything, flags last the session — showing a tutorial once per visit is mildly annoying, while never showing it strands a player who arrived from a link with no idea what the controls are.
