In the language selection screen you have the option of choosing Fremen (remember the Frank Herbert's Dune saga). Selecting Fremen as the game language actually works, and it's quite funny to read all those pseudo Fremen text.
You can see all the artwork used in the game including the animations if you have an image viewer capable of displaying Deluxe Paint PC files (.LBM). These files are stored in the directories PIC and SPR.
You can also listen all the music tracks with a MOD player. Just rename all the files' extensions from .KMD to .MOD in the directory KMD.
