ALUNA RIFT IS COMPATIBLE WITH STEAM DECK!
Whilst waiting for official verification from Steam (which to be honest, may be quite some time, if at all) - I thought it worthwhile to clarify that Aluna Rift is fully compatible with the Steam Deck.
Here is a video that my friend kindly took the time to record of him playing the game on his Steam Deck.
