So, that works, that’s how I’m running the game.
What I’m saying is that I cannot use the Itch app to install and manage it because of this bug – which is quite simple to fix, but it must be done before zipping the package.

No problem.
The Itch app manages game installations and updates, but if the game executable is not executable on the current architecture, the app refuses to install (or update) the game.
So, before you make the ZIP package, you need to set the file executable flag, only after that, you can put it in the ZIP file.
This is precisely the chmod +x redux.x86_64 you mention, but before zipping the package.
