Fondant

They actually released it recently, there are controller bindings in the settings and you can play with a controller

i recall reading somewhere that the rumble on the steam deck is actually the haptic feedback motors and that is why it is weak

you can use a url to an image and put the twitter link to the actual source in the body to make the thumnail show up and have the source on top (put the imgur link in the url field and the twitter link in the body)
