Last semester I created a lot of concept art for our Prototype Ikigai. In our first drafts, we wanted our game world to be colourless. The player was supposed to use his spirit power, a freely in flight movable sphere, to solve puzzles and help both Yokai and humans. The Yokai would follow the player, displayed in form of a counter and the world would become more colorful with every good deed. At some point, differently colored Yokai would then unlock new features of the spiritual energy, indicated by the spirit spheres color. We implemented most of the mechanic basics in our prototype, that represents the spirit forest as start of the game. The only thing we had to let go of was the hand tracking in order to move and shoot the spiritual energy due to technical challenges that could not be overcome in that short time.
