Hey, I'm a Steam Deck user & Zortch is super rad, but its gamepad support is kinda wacky. Analogue movement isn't supported, instead the game just translates the digital cardinal directions & diagonals to the left stick, & all the default mappings for everything else are very non-standard & really weird (e.g. LB to fire instead or RT). The game does let the user remap all buttons, which is good, & on Deck I've also got the per-game SteamInput API I have at my disposal, but yeah.
