Have you tried running the game on Linux? I made it on Unity and it might be that it will simply be working - I haven't tested it on Linux.
No, the file is an Windows executable, you have to export to Linux and provide a Linux executable, if you are willing to. I could try to run it via WINE, but then it's not native Linux.
I hear you. I uploaded a Linux build, so do check out whether it's working.
Thanks ! It's broken. I can DL and launch the game, then i can access the Credits and Options menu, but clicking Start has no effect at all. No error, nothing, just nothing happens.
