If you've enjoyed the Snail Trek series and want to support to the developer so they can make more games like this, the Rainbow DLC is available for chapter 1. It outfits the main character into moving rainbow colors (can be disabled in the Options dialog), and adds an entry into the ship's missing computer page. Also, don't forget to check out the Disco DLC for chapter 4!
