Played on Steam Deck - Compatibility Mode Proton 7.0-6 - works like a charm though the resolution is a bit off so you can slightly see text-box assets on the top and bottom that are supposed to be hidden.
Edit: Using steams launch options to force 1280x720 as resolution fixed it and now it looks as beautiful as intended
It's such a fun Jump & Run and full of potential to be expanded. Really brings me back to the good old N64 days. Would play more of it anytime!
