Really impressive! even to the point of producing a manual and some great artworks! I loved all the tests and their Game Boy visions, it's very well transcribed. I do one live per week on Game Boy homebrew, and I'd love to do one on yours, I've already got the next 3 weeks scheduled with games, but I think I'll do it before the end of July if you've got networks or anything else you'd like me to put forward don't hesitate to let me know :)
