Progress
Stars, hidden levels and how the trail opens — none of them lock the way forward.
Stars
Path, Master and Trace: three separate goals. None locks the next level; Master is hard on purpose.
Hidden levels
Two per act, opened by collecting relics. They teach no new rule — they ask you to be good at the ones you know.
Hints
Three tiers, all free, none of them costing a star. The game measures when you are stuck but shows nothing unasked.
