Mint 21.3
I've downloaded, unzipped, and double-clicked the thing named "Hyperspace Dogfights". It shows a dialog asking if I want to run or display the file. I've tried running 'In terminal" or just "run", and nothing happens. If I "Display", a text editor appears showing:

#!/bin/bash

export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH

./ExeLinux

So I tried running ExeLinux. No response to double-clicking, and if I open a terminal in the folder and type "ExeLinux" I am told "command not found"

WTF am I missing?? I'd love to play this game!

OK so WikiHow says "add ./ to the start of the file to run it". So I typed in "./ExeLinux" and the following error occurred:

./ExeLinux: error while loading shared libraries: libGDCpp.so: cannot open shared object file: No such file or directory

I guess this is progress? How do I fix this error? I can see a file called "libGDCpp.so" right there in the directory using 2,339,016 bytes of storage, so IDK why it's not being found.

OK found the fix: https://itch.io/t/1980744/linux-issue

Dev, please include a readme with explicit instructions for how to actually run this game, in case access to the forums is ever lost or we are trying to play it offline.
