Gameplay
In the game, as in all Puyo games, groups of two colored blobs (in this case, sprites of the beans from Dr. Robotnik's Mean Bean Machine) fall from the top of the screen. You must rotate and move the groups before they touch the bottom of the screen or the pile, so that matching-colored blobs touch from above, below, the left or the right. Once four or more same-colored blobs touch, they will disappear, and any blobs above them will fall down to fill in the space. If a player manages to set off a chain reaction with these blobs, rocks will fall on the other player's screen destroying it and causing them much woe. The number of rocks that falls depends on both the number of blobs popped and the number of consecutive chain reactions. These rocks will only disappear if a player manages to pop a group of blobs that are in direct contact with the rocks.
Notably, in the cinematics between each round, Kirby is shown trash-talking his opponents in full sentences. This differs greatly from other Kirby games, where Kirby hardly speaks at all and is also much friendlier in general.
