Two-Lung

Breathe or crash.

Two-Lung is a breathing endless runner. One tap switches you between two
states that flip your physics completely, and staying alive means switching
at exactly the right moment.

Inhale — light and floaty. You puff up, jump high and hang in the air,
fall slowly, and glide safely over wide pits and across fragile glass floors.
But the wind pushes you around, you can’t break anything, and low ceilings
punish your long airtime.

Exhale — heavy and fast. You compress, drop fast, and smash straight
through cracked walls and headwinds while hugging the ground under tight
tunnels. But you plummet over gaps and shatter fragile floors into the
hazards beneath them.

The world alternates between sections that demand lightness and sections
that demand weight, faster and faster the longer you last. Obstacles are
colour-coded to your two breaths, so you read the run at a glance — no
tutorials, no text.

Breathe on the beat. The soundtrack has a tempo, and switching in time
with it builds a Flow meter that raises your score multiplier and layers up
the music. Skilled play converges on breathing in rhythm — and the world
subtly reshapes to fit players who do. It’s a runner that feels like a
breathing exercise at high speed.
