Lantern Grove
Light three lanterns. Wake the old gate. A small example of interaction, state, and clear feedback.

What this mechanic teaches
Stable object IDs, a guard against repeated rewards, a gate rule derived from actual progress, and a complete reset. Try a reset and watch how the progress starts again.
