Description: Ark Mobius is a gal-game that contains beautiful girl, rhythm and multiple endings. In 2320, black goat, a huge humanoid monster with tentacles suddenly appeared on the earth. She fell into madness and made human beings attack each other through mind control. Only magical power could damage her. However, due to excessive industrial development and pollution, there is not much magical power left on the earth. Therefore, as the container, you need to travel to other worlds to obtain power against the monster from various beautiful girls and save the human being. Ark Mobius contains easy yet fun rhythm elements. You can finish them by mouse. It also has various traditional 2D side-scroll scenes, diverse enemies and beats. (headphones are strongly recommended) We also provide a "Lock HP" function for players who are not very good at rhythm games.
