If you're trying to find this game in your distribution's repository, you're wasting your time. Just download it from the link in the first post, unzip it to a convenient place (for example, create
Games folder in your home dir, and put it there), and run the
beatbanger.x86_64 file.
If you want to create a shortcut in the apps grid / start menu, you can create a file
beat-banger.desktop in the folder
/home/YOUR_USERNAME/.local/share/applications/, with the following contents:
INI:
[Desktop Entry]
Type=Application
Version=1.0
Name=Beat Banger
Path=/home/YOUR_USERNAME/Games/BeatBanger
Exec=/home/YOUR_USERNAME/Games/BeatBanger/beatbanger.x86_64
StartupWMClass=beatbanger.x86_64
Icon=beat-banger
Terminal=false
Categories=Game;
Optionally, you can add an icon to the "/home/YOUR_USERNAME/.local/share/icons/" folder.
