This unique puzzle game combines the classic gameplay of 'Puyo Puyo' with the mascot character Haro from the 'Mobile Suit Gundam' franchise. In Haro no Puyo Puyo, the falling blobs (Puyos) are replaced by colorful Haro robots. Players must stack and match four or more Haros of the same color to clear them and send 'garbage' blocks to their opponent. The game features a cast of Gundam characters represented in a cute, super-deformed style (SD). It includes a Story Mode, Endless Mode, and multiplayer battles, offering a charming twist on the competitive puzzle genre.
