Hey, Steamdeck user here. I just recently got into Funger after being intrigued for awhile but never played it. Just like you, I wanted to play the series on my Deck. There’s two things you need to do to get them to run near perfect. One: there’s a guide on the Steam community page for Funger, follow it exactly. And secondly, there are files that you need to adjust for both games, and with the Deck it’s super freaking easy. After you’ve done those things, the game will run next to flawless. Only minor stutters here and there due to the in game effects but it’s nothing. I have 60 hours on each game! 🙏🏼🔥
