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 :/
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.
Can't say for sure. I haven't touched Windows for quite some time, Plus-X, as BloodScourge suggested, might be your best bet. If that doesn't work, I made a crude script that sets executable permissions for the user and then runs the game. Hopefully that helps some.
#!/bin/bash chmod u+x chrome_crashpad_handler nacl_helper nacl_helper_bootstrap somnaBuster ./somnaBuster
I'll do some research on the subject and get back to you if I find anything helpful.
