Honestly haven't played that much - I spent way more time on (and have more thoughts on Ms. Pac-Man.

I did implement a browser version of this in JavaScript during my Xerox internship in 2003. It was slow but fully functional - I didn't really know what I was doing, so I think I just created a ton of absolutely-positioned image tags and moved them with the script, doing all my own collision detection, etc. I wish I'd kept it!
