itch.io

Some 18+ games implemented "your patch version is old -> update" button in game Menu screen to simplify update.

Obviously button doesn't appear if patch isn't manually uploaded first time manually (triggered only if file is present, upon version mismatch check) .

Would it be too risky to implement something similar ?

File update on SteamDeck implies switching to desktop mode, downloading file via browser (not Itch client ) ,which takes a little bit of time.
