Gorogoa

In Gorogoa players are presented with four images in a grid and must stack, combine, and explore each image to find a connection between them in order to advance and open new areas. Players are not guided through the process, as the game contains no language, and must work out what they need to do to finish each level. The plot involves a boy seeking an encounter with a divine monster, exploring themes of spirituality and religion. (wikipedia.org)
