No space shooters huh? Tough one, thats like my fave-o genre.

Hmmmm lets see. Maybe I can help with platformers?

I really liked "Gold Digger"!! Pretty sure its free/shareware. It will fit on a floppy too!

"A day at work" is kinda cool, but really just degrades into violence pretty quick.

"Super Maze Wars!" A shooter, and not technically maze anything, but I killed K's of hours on that.
