Aritana is a platform game which the main aspect of its mechanics is the possibility of changing your stance. This stances define attributes such Speed, Jump Force, Attacks and Special Abilities. The player must choose between these stances to overcome obstacles and fight the Spirits of the Forest in a quick, intuitive and fun gameplay mechanic. A tribe of brave warriors lies deep inside the Forest. Tabata, the Chieftain, is terribly sick and Raoni, the Wiseman, is taking care of him. A powerful Forest Spirit took over Tabata’s body and only an ancient ritual can undo the spell. Unfortunately, the most important ingredient is missing: a feather of a rare harpy named Uiruuetê. Aritana, against Raoni's decision, embarks in this dangerous mission. The sacred feather can only be found at the top of the highest mountain, through the lands of the man-eater Mapinguari.
