Tier 0 — always visible store facts
Tier 0 is public marketing: thousand-plus puzzles, four worlds, colliding mechanics, named design foundations, and the existence of a PC demo. Nothing in Tier 0 is a room solution.

Tier 1 — design-game blurbs (optional)
Tier 1 repeats Steam’s one-line descriptions of Mirror Isles, Skipping Stones to Lonely Homes, Promesst, and Heroes of Sokoban. Those lines describe other released games that Thekla names as foundations. They are not OSS answer keys.
- Mirror Isles: swapping places with reflections across islands (Steam’s wording).
- Skipping Stones: stones in water as stepping paths (Steam’s wording).
- Promesst: cave with mysterious beams of light (Steam’s wording).
- Heroes of Sokoban: hero classes, movement and pushing to an exit (Steam’s wording).

Tier 2 — demo solutions (empty on purpose)
Tier 2 is reserved for puzzle solutions that someone on this project actually completed in the Steam demo and recorded with a reproducible path. That set is empty. This page will not fill it with guesses, datamines, or unnamed “community” answers.
Unknown beside this fact: No demo puzzle ID, input sequence, or screenshot-based solve has been verified for this atlas.
