I just tested it and it's running fine, I thought it wouldn't even enter because after the "???" say "Whatever the case, I'll be waiting" took a while to open the loading screen.
I noticed that the fps is low, so I lowered the resolution and it ran smoothly.
In this part of the slower running it could be the bad hardware as I have an integrated intel gpu. It would be nice if you could release a version with an OpenGL like 2.1 which is older for bad computers, if it's not too much work.
I know that at Godot it's easy, there's an option with an interface to change OpenGL. But I don't know how it works in Unity.
Anyway, the game runs, the only thing I had to do to enter the game was to right click >>> Properties >>> check the box "Allow this file to run as a program", Or in the terminal type "chmod +x ADS_Linux.x86_64".
