This might be a bit late, but on the Itch.io desktop application, you download the Windows version and run the game on Linux. After downloading the Windows version, run the game and select "DUST.exe".
It will either:
- Run after a couple seconds.
- Stay stuck at launching.
If it's stuck at launching, force close it by clicking on the game and clicking "Force Close" and try again. It will usually work the second time around for some reason.
Hope this helps.
