Last week we shared the first episode of a neat mini-series from the PBS Game/Show YouTube channel, which aims to break down and explain the secrets to the great design in Super Mario games. Episode 1 looked at 'hidden language', while episode two looks at the manga-inspired structure in these games.
Those that follow the background to Shigeru Miyamoto's career may already know of the influence that kishōtenketsu comic panels had on his design principles. This video does a good job of explaining that in some detail, showing some of the practical ways that approach works in Mario level design.
If nothing else, it's a reminder of how we can all come up with better levels in Super Mario Maker.
