I am a bit of a newbie with distributing applications on Linux. I managed to get it installed and running on my Ubuntu machine. However the games are free, with zero revenue so I’m not spending too long on it. Instead of figuring out how I should be installing it, here’s some files and good luck!
What I think you need to do:
Extract to a decent location where you want to keep the install, for example /home/User/GAMENAME, substituting your own users.
Run the .sh file to create a desktop icon
