FLOWER-PON! -ヘタDEパズル!-

This is an easy-to-understand puzzle game with a storyline where
you pair up from among the four characters and use that combination to advance the story. Defeat all the enemies that appear and escape from this world as quickly as possible! Opponents may also pair up and challenge you to a battle. If you find yourself in a pinch, fight back with your special move!
