The historical preview identifies Moongolow as a challenge stage built around limited hands and discarding. The later official release FAQ confirms the hand-size modifier is active on first playthroughs of Moongolow and Moongohigh, then optional once its Relic is found.
Treat the released stage and optional-modifier status as official, while keeping route, unlock-location, and build advice caveated until direct play verification supports it.
