We have removed the native Linux build of Mida's Adventure in favor of using Proton's awesome compatibility layer to run the Windows build. This currently seems more stable and easier to maintain.
To run Mida's Adventure on your Steam Deck or Linux device, inside the game's Steam settings, please force compatibility using Proton 9.0-4 or newer.
The game should look and play great, as it did previously, with full controller support.
Please let us know if you experience any issues.
