This is a great project in order to bring in new programmers. It's so simple, but so entertaining. If fun little "toys" such as these keep popping up, it's sure to create more interest for the rest of the population. :)
I hope this will be included in future Shoes versions. Shoes is already awesome for making (portable!) retro-games. This will add another great deal of retro-ness. ;)
He wrote it for Hackety Hack, which will be built on Shoes for its next version. Whether or not it's included in Shoes itself or just HH will remain to be seen, but I'd love to see it in the former.
