Temple Of Vel-Cro is a Game Boy game by infected_bytes.

This is the story about the Irish sheep Sticky Hooves. He and his girlfriend Marry came to America to live their dreams!
They’ve spent all their money to start a new and better live, but unfortunately Marry got sick and because of the bad health care system, they can’t afford the treatment. Of course there was only one way to pay their debt… Since Sticky once was an archaeologist, he travelled to ancient Mayan temples in order to find their treasures and to pay his debt!
