Tips on how to play the game under Linux:
a. Make sure that the executable (GOTOUBUNRE.sh) is executable (using chmod +x GOTOUBUNRE.sh).
Alternatively: bash ./GOTOUBUNRE.sh will do the same thing if you don't need to change the permission.
b. Run the game under the same directory (e.g. /home/<username>/Programs/GOTOUBUNRE-5.0-pc)
c. Instructions unclear? (ignore the wrong spelling of the executable, and also the color because I suck at picking colors at this point)
