Concept: Play Puyo Puyo Tetris in swap mode, but with two players and you pass the controller back and forth whenever the game swaps

the non-playing player can use the time to form a plan for when play returns to their field

what do you mean

I think Prof meant two players per team

yeah

co-op

Would make some of the high-level coordinated tactics of top-tier Swap play harder to pull, but becuase you can see the inactive board, you can plan, so it would produce matches that play out MUCH differently.
