Pingus script to play extra levels

Pingus is a nice Lemmings clone. Many of the levels are loadable only by the level editor or command line. You can also create custom Levelsets, but whichever method you use, they are all somewhat cumbersome.

I found a nice bash script here that loads individual levels and used it as a basis to create my own with some improvements. The new script gives you the option to open Pingus normally or select an individual level.

1. Change the PINGUS_DIR path to your pingus binary

2. Edit the Pingus command line parameters a few lines down (/pingus $f -g 1280x720 -f) if you want to change screen dimensions, etc

#!/bin/bash
