Hello CubeCreatorFan! A suggestion I have for the game is that you could (maybe) change the textures of animals to their Minecraft counterparts (if you are not busy)? Other than that, your game is impressive; keep up the good work!
i gotta say, the steam deck isn't a bad deal, even if you get a used one, you have options to get it serviced and the parts are also available through ifixit
