When I was starting a new project to take my 4K game and turn it into a 32K monster yesterday, I noticed something odd.  My code would not  compile.  On further inspection, I had forgotten to include a custom class in my new project.  A custom class, that is, that was totally unecessary.  By removing that class reference, I gained by 800 bytes!

Suddenly, my “finished game” was not finished at all, and could be enhanced even further.  Using my new coding mind-set, I was able to gain the folloing with those 800 bytes (with 20 still left over):

• A new sound.
• Expanded text instructions 
• Expanded text messages
• Glow filters on most text
• The ability to [Pause] the game 
• The ability to earn extra lives
• A new feature: Shooting and the abilty to collect shots.
• Various game balancing fixes
• Bonus: I also fixed a major new-found bug and added code to prevent some odd behavior.

If you told me two weeks ago that I could fit all that into 800 bytes as an after thought to an already finished game, I would have directed you towards a decent looney bin.
