The game runs without any issues out of the box. It seems to be a straight port of the Switch version, so it doesn't offer any graphical options and is capped at 30fps. But the game has so few 3D models that it's not an issue at all. The only visual issue is that character models appear aliased at 720p. I advise forcing the resolution to 1080p within SteamOS (both internal and external display) to provide some form of AA through supersampling. The game is so light to run it won't greatly impact battery life and the framerate will remain locked at 30. The only mild annoyance I had was that the game does not seem to save controller configuration done through the in-game menu. Use Steam Input instead if you need to change anything (I changed the net to the triggers instead of the bumpers).
