The Girl lived in Yin while the Boy lived in Yang. They must across the Styx to reunion. This misfortune couples share only one soul, the soul power must be transferred from one to the other reciprocally when overcoming the difficulties in this journey.
This is a networked two-player game. The boy can attack the devils and the girl can fly over them. But only one player can have his ability activated at one time. So the players should communicate to each other. When one is in trouble, the other should pass the energy to him.
Team members includes Beibei Liu, Zhongyuan Liu, Qian Zhou and me. We made it in 48 hours during the Global Game Jam 2018.
