Gowin (高遠科技有限公司), also known by their brand name "Hot Kid", is a Taiwanese game developer/publisher of unlicensed Game Boy and Game Boy Color games. Some of their GB titles were developed by a team with connections to Gamtec and Vast Fame, while some GBC titles were developed by an unknown team in mainland China.
Their mascot is a green dragon named Guagualong (瓜瓜龍), who even becomes a playable character in later titles (mainly the Binary Monsters trilogy).
