It's a meme game made by one dude with UE5, so I wasn't expecting much, but I wanted to see if Steam Deck could handle it. While it is playable, the performance is very poor, and there's no built-in support for controllers so you have to create a custom layout to map the buttons correctly. This means you don't get analog movement, but you're also missing the precise camera control afforded by a real mouse. Overall, much better to just play on a PC.
