Released as a launch title for the Game Boy Advance in 2001 Castlevania: Circle of the Moon represented a huge graphical leap forward from the previous handheld titles in the series, thanks to this new hardware.

But have you ever wondered what would have happened if it was developed for the Game Boy Color instead? Well, you needn't wonder anymore! Thanks to the efforts of the game developer and Castlevania fan Ryan Marcham (@Diablohead on Twitter), we're now able to play an interesting "what if" that reimagines Circle of the Moon as a Game Boy Color game

The demake was created using Game Boy studio 3.0.3, as a test of the creation tool, and reimagines the first area of the game: the catacombs. Playing as a newly sprite-d version of Nathan Graves, you'll be able to make your way through this area, killing bats, skeletons, and bone pillars, while collecting hearts, potions, and daggers from the ground. It also features a terrific reinterpretation of the original Catacombs theme, courtesy of Malcolm Broon (@DragonXVI).

The demake was released earlier this year in April but must have skipped us by. Recently, one of our readers made us aware of it on Twitter though (cheers @JoelJGames!), and we felt it our duty to pass the info along. You can play the game now in your browser or download a Game Boy Color ROM from
