A victim of a demonic influence will have to choose between the evil powers offered or rejecting them in favor of developing heroic talents. Dangers and enemies will become more fearsome in battle throughout, increasing the temptations to acquire more power by giving up part of the hero's soul to the demon while progression of the demonic influence will be reflected by the transformation of the hero's body. The game features three endings, depending which choices the player made during the game. In the finale the player's actions determines which ending will play out: the sacrifice ending (involves the player rejecting the demon's powers and killing themselves), demon ending (the player becomes a full demon thus destroying the world of Vertiel) and the king ending (the player exterminates the demon and becomes the ruler of Vertiel).
