I have made a Flatpak for Dweller's Empty Path and Escaped Chasm, but since the files are kinda heavy and I'd like tem to post them on the itch.io page as a download option, here is, for each game, a patch file and info on how to build the flatpak on your own computer
EmptyPath: https://gist.github.com/Thesola10/0c89552488ef37b3c49fd75f1000d597
Chasm: https://gist.github.com/Thesola10/caaf776545719a888b9542db2a1f3bcd
Basically boils down to packaging both the game and NW.js in a flatpak to eliminate per-distro issues with node
