PuffRise

Hold your finger down and the balloon climbs. Let go and it sinks. That's the entire controls, which is why it's so unfair when the gaps between clouds start shrinking. Slip through cleanly and it's a point. Brush a cloud and a life pops, three to spend. The balloon has a mind of its own, drifting sideways right when you need it still. You learn to feather the button — little taps instead of holds — until the screen fills with gaps and your breathing syncs with the rise and fall. Then one gap too small, and down you go.
