This game is intended to work with on smaller screens such as the steamdeck, although was intended for use with a mouse the touchpad and touch screen are usable though some users may find the coordination challenges a bit weird. If you are familiar with the touchpads on the steam deck you likely will have very little issues. The resolution scaling and UI mapping is causing some hiccups when downscaling to the steamdeck size however there will be continued efforts until resolved to integrate it....
