Just wanted to mention that I agree with Colin and you should try to package your games so people don't have to download something extra. It's a bit of a pain and just makes it less accessible, especially to anyone who doesn't know how to use the command line. I like that you restricted yourself so heavily, it definitely must have been a design challenge! The controls aren't very intuitive though; I like that you matched up the colours on the xbox controller, but although the keyboard uses fairly traditional keys it's kind of difficult to remember which is which for the colours (I'm sure with practice I'd get it lol)
