Prolific indie game developer Jonatan "Cactus" Söderström (Psychosomnium, Clean Asia) put up this new trailer for Tuning, specifically created for the puzzle platformer's IGF 2010 Main Competition entry. Even with more than twice the footage than the last trailer, it still looks super confusing!

Cactus describes Tuning as a platformer in which the levels are "gradually presented weirder and weirder, creating visual puzzles where the player has to figure out how what he sees relates to his own actions in the game." Here's a photo of Katamari Damacy/Noby Noby Boy creator Keita Takahashi trying to figure the game out!
