Thanks for the wishlist! I've taken from a lot of stuff for this game. Naissancee (and indirectly Blame!) are the main ones in terms of aethetic. The strange liminal vibes of stuff like Inside and The Beginner's Guide is also something I want to capture.
I don't have a steam deck, but I'm developing on Linux so a native Linux port is a guarantee, and I'm aiming for full controller support. So it should work pretty well.
