I'm curious too because the control is listed but the "S" key is also the key to open Patreon. That would be a weird feature to lock behind a paywall since it's only a "quality-of-life" type change.
Where is a fullscreen option listed? I did experiment with including one, but it never made it into any released version of the game. It’s not in the patron edition either.
There is no fullscreen mode, but you can use F11 in most browsers. On the PC version, the best you can do is maximizing the window. This is a feature in the Hex version of the engine. I may backport it, but it’s low on my priority list.
