Same question. Just tried demo and seems quick. Planning to try along with Meta Quest 3.

Runs great on Steam Deck, editing will almost surely have to be done on desktop. Game doesnt support cloud saves, but the only things that "save" anyways are SNES/Gameboy game saves and your high scores in cabinets. I play both Desktop VR and on Deck. Deck even holds 60FPS at 1200x800 if you drop view distance, particle quality and (maybe) shadow settings down one notch from their default.

Set the game to borderless to avoid funky window sizing.
