I couldn't play on linux :(
I tried to run it on the terminal to check for errors and this came up.
I'd suggest you embed the PCK file to avoid these type of error.

Ah, sorry about that. Don't have access to a linux (or MacOS) machine so I couldn't test either before uploading. Unfortunately I probably won't be able to do anything about it this game but I'll keep this in mind for any future Linux exports.
Edit: Obviously if you do have access to a Vulcan capable Windows machine I would encourage you to try it on that, since so far that seems to be the only version working properly.
For what it’s worth, I was able to get this working on Linux without any problems. I’m using Pop!_OS (Ubuntu-based) with proprietary Nvidia drivers, so it seems like a pretty different hardware set up. Could potentially related to using the Godot 4 alpha as well.
Just throwing it out there in case it’s helpful for anyone.
