So, the first release has emerged, and I've changed the name of the collection.
It's no longer a Green Retro Collection, but instead a Platdude one.
Worry not, the games haven't changed. In fact I've even created a special page for it.

The Platdude's Retro Collection page lists EVERY game that's in the package.
So, that's the 6 that are in there right now, and also 2 in-development additional games that will be in the next release. I'll probably forget to update that in future! Oh well.

So that's the release. It's fun! Enjoy.
