Just found the site here, thanks for adding flooder and Alien Invasion to the list
I see there are still a lot of links to catskull his shop, but they stopped selling homebrew games.
For the game boy a lot already moved over to other webshops.
DMG Deals Damage and Sheep it up have moved to yastuna games https://yastuna-games.com/en/14-nintendo-game-boy
Petris, Death Planet, Tower of Hanoi and Quartet have moved over to my shop https://www.ferrantecrafts.com/shop/36078980/game-boy
Dino's offline adventure will follow in the coming weeks.
And there is also a new game that is not on the list yet. Color Lines.
