Hey! Pikmin stands out from the rest of the Pikmin series primarily due to its shift in gameplay style. Unlike the traditional Pikmin games, which are real-time strategy games where players control a group of Pikmin to solve puzzles and defeat enemies, Hey! Pikmin adopts a 2D side-scrolling platformer format. In this version, Captain Olimar moves through linear levels, using his Pikmin to assist in overcoming obstacles, collecting items, and solving puzzles, but with less emphasis on large-scale management and real-time strategy. The game also introduces a more casual and accessible approach, with simpler mechanics and a more laid-back pace compared to the complex, real-time resource management of the main series.
