The shipped 1000 levels have a hole: 568 of them need no rotation at all, and none needs more than two — the mechanic the game is built on is mostly decoration. This fills the empty band with levels that need at least three. createDeepLock builds a four-piece chain where each link only releases at a later orientation, and growDeepLevel packs the rest of the board around it without opening a shortcut. Candidate pools are built per orientation and left untruncated; ranking by bend count first starved the packer and capped levels at four to six pieces instead of twelve. deadTurnAudit enumerates every reachable (orientation, remaining-set) state to prove no dead ends exist, and counts how long a player can be left with nothing to do — solvable and feeling solvable are different things, which is what "level 2 is impossible" turned out to be about.
