If Studio Ghibli made licensed games for its films instead of collaborating on original titles (e.g. Magic Pengel, Ni no Kuni), this is what one of them woud sort of look and sound like! That's presuming the famed animation house would create a game for a 2008 film like Ponyo on a 1998 handheld like the Game Boy Color.

Feegrita Sinclair and Mee-lin created this short video for a school project, animating Hayao Miyazakis' charming goldfish-becomes-a-human-girl movie as an 8-bit title, throwing in some Super Mario Bros. sound effects and a chiptune-style arrangement of Joe Hisaishi's score. I would be down for this.
