I really enjoyed this little competition, reading everyone's ideas and having a chance to flex my creative muscles a little bit.
“Is anybody implementing their game?”
If I ever do, it's pretty far down my list. I created the idea quickly, without any plans to follow-through, but it seems pretty well-received, so maybe someday...
I'm working on a simple puzzle game right now to hone my skills, though. My programming is a bit rusty.
