Thanks, glad you like it! Hmm that's weird, it should just work. I guess Godot's input handling somehow isn't picking it up. If it's a Windows or Linux handheld (aka not Android, which yes is technically Linux too but you know what I mean lol) you could try adding the downloadable version as a Steam game (click games in the top bar, then "Add a non Steam game to my library"), and then run the game from Steam, since that should make it use Steam Input, which might fix it.
