A VS Puzzle Duel game that plays slightly like Panel de Pon/Tetris Attack series (but in many ways it's a variant of Taisen Puzzle Dama)
There's a board of balls and squares, you use a little floating cursor to "switch" the ball/square, when the Balls match up in threes, they clear and also trigger nearby squares for chains. Although I am still needing to get familiar with chain set up.
Like Puyo Puyo 20th Anniversary's Ice block mode, each character has specific drop patterns.
The bout is won/lost if one sides entire screen fills up. There's a hard quota time of 150 seconds until the ball spawning accelerates to max.
