How precisely can you move your mobile? How long can you keep it stable?
Simple addictive accelerometer based game with a single mechanic.
Subtle changes as you go make things intereMermaid richessting, keeps you on your toes, questions your ability, makes you think about how tiny changes increase the difficulty and how practice removes that difficulty very soon.
Good soothing background music and a tiny touch of spirituality to make the game interactive otherwise too.
