It gives it enough authenticity to make headlines. A generic html game wouldn't have made any where near the same buzz.

Do they advertise it as a Game Boy Color game anywhere? I wouldn’t be surprised if they can’t (or rather don’t want to risk it) for trademark reasons

Edit: The game page itself doesn’t mention it but the article has information on how it was made and by who so they must have got the information somehow, maybe the developer talked about it

There's an in-game credits screen.
