See Puyo Puyo vs Tetris in action

It was a mad idea to start with, and looks increasingly frenetic in action as players flip between games modes, with the outcomes of one influencing what happens in the other. With the Vita rather lacking in fun little jollities like this, here's hoping that dense Japanese text won't stop Sega from posting it our way soon.

Note, look for the Roger Dean and Alexi Pajitnov credits at the bottom, who'd thought it however many decades on.
