Sorry for the late response. I provided the Linux version I used for SteamDeck compatibility as-is but don't have a way to test it myself, as I don't use Linux. I couldn't find anything helpful searching your error code or the 'permission denied' bit.

I'll add a notice to the Itch page for others so they don't make an accidental purchase. Itch offers a refund policy if you contact them directly. If I can offer anything else as compensation for the trouble, let me know. Sorry :/

Thanks, I appreciate it. I'll do some research of my own and see if I can come up with anything. Worst case scenario, I'll just run the Windows version through Wine.

I get the same error with the Itch build: it's due to the fact that on Linux file extension is secondary/cosmetic (contrary to Windows) and files need to be marked as executable to run. The Steam build launches fine on the same machine because every file is marked executable (not ideal but hey). Now, the easy way for you would be to use plus-x by Cheeseness and mark the following files inside the zip archive as executable:

- linux64/chrome_crashpad_handler

- linux64/nacl_helper

- linux64/nacl_helper_bootstrap

- linux64/somnaBuster

Hope that helps.

While using plus-x didn't seem to work for me for some reason, I can say that manually making those files executable does make the game run now (thanks for that).

plus-x acts like the permissions are changed, but when I extract the zip file, the changes don't stay.

Hmm, works for me. Maybe try directly from command-line:

$ python plus-x.py somnaBuster_itchLINUX.zip +x linux64/chrome_crashpad_handler linux64/nacl_helper linux64/nacl_helper_bootstrap linux64/somnaBuster

Nope, same deal
