The journey
Three acts, three regions, and why the difficulty climbs between them — all read from the level catalogue.
The road runs through three acts, and each act is a region: a covered bazaar and caravanserai yard, desert and oasis, a mountain pass. Each brings its own rules and builds on the one before.
The Acts page walks through the regions, which rules arrive in each, and the curve every act follows: single-rule introductions first, then combinations, a peak, and a finale that leads into a story scene. How the difficulty climbs explains that nobody decides by eye whether a level is hard. The game’s own solver measures every level, and each one has to sit inside its act’s band or it does not get into the repository.
The next act opens when you finish the main levels of the previous one; you do not need to collect stars.
Acts
Bazaar, desert and mountain pass: each act brings its own rules and builds on the one before.
How the difficulty climbs
Difficulty is measured, not dialled in: minimum moves, state space and dead-end rate are held to bands.
