Marooned on Earth, Milo discovers he is far too small for the world around him, with every person gone and the calendar apparently stuck at 1991. To get home to his own planet and return to his proper size, he crosses a sprawling, human-scale world and recruits hundreds of tinykin, small creatures that each have a distinct power, to reach new places and solve problems.
Beyond the platforming and puzzle solving, the adventure is about uncovering what happened to Earth's people, and finding that out matters as much as the trip home. Single-player, with full controller support, it suits players who enjoy exploring colorful spaces and collecting things at a relaxed pace.
