The Linux version seems to be missing a file. It's not executing.
I can confirm that the download itself is fine and includes the "nw" executable! It could be possible that whatever software you are using is having an issue extracting the archive properly.
its on steam deck Desktop using the itch.io Launcher for Linux and downloading the Linux version of the game.
EDIT: Found the issue. The game doesn't run on Arch Linux Which is what Valve is running on the Steam Deck
Error code 0xffffffff (-1) for (nw)
