Like its sister collection A Buttload of Free Games, A Handful of Lewd Games supports Steam Deck (and Linux via Proton) as best it can!
If you encounter any issues running the game on Steam Deck, please leave a comment in the bug report discussion topic and I'll do what I can to get it fixed! Not every game in the collection supports Steam Deck, but I do what I can to make as much as possible work.
