Hotel symbol order

PowerPyx lists this sequence: Bird, Tree, Planet, Bird, three-legged triangle, Satellite, Satellite, Fish, Rocket, Planet, Dog, Pillar. The source gives the corresponding button positions as 21, 17, 9, 21, 12, 24, 24, 5, 9, 1 and 14.

The user-provided 100% Guides video was checked at 1:24. Its on-screen step says the route is New Game+ only and points to Room 621 for Strange Book 3. The frame supports that step; the written guides remain the sources for the full sequence.

Ending effect

The cited guides say the Sci-Fi ending triggers before the usual final boss and skips that fight. The in-game item name differs between sources, so use the access-card item obtained from the hotel puzzle rather than relying on one label alone.
