Puff is a relaxing yet explosive one-finger physics arcade game: charge a pressure cloud, aim it and release to shatter neon shapes into glowing shards. Casual, offline, no ads.

Hold. Drag. Release.

Puff is a minimalist neon physics game. Press anywhere and a pressure cloud grows under your finger. Drag it to where it matters. Let go, and the pressure blows apart the geometry drifting in from the edges toward the core in the middle of the screen. Let one shape reach that core and the run is over.

It all comes down to one question: when do you release?

CHARGE, OVERPRESSURE, REGRET
The longer you hold, the wider the cloud grows and the harder it hits. Hold past the overpressure line and it fizzles instead — no shockwave, no points, and a penalty on top. The rim flickers through the last quarter of the charge, so an overcharge is always your own call and never a surprise. Shapes that drift into the cloud while you are still holding drain the charge back out of it, which turns every long hold into a bet: a bigger blast, or nothing at all.

Nothing is on a timer except you. No cooldown, no ammo, no menu between you and the next release.

FOUR ENVIRONMENTS, ONE CONTROL
The same finger does something different in each of them.
• Vacuum — nothing is damped, so every blast is a slingshot and a shard keeps whatever speed you gave it. Nebula bands, three parallax star layers, the odd meteor.
• Air — light gravity and a wind that shifts across the screen and quietly bends everything you fire. Haze banks, wind streaks, drifting dust.
• Water — blasts become short shoves, everything sinks slowly, and you end up planning two releases ahead. Surface caustics, light shafts, rising bubbles.
• Plasma — arcs jump between nearby shapes on their own, whether you fire or not.

THINGS ACTUALLY SHATTER
Shapes do not fall apart into pre-baked pieces. Each one splits into convex shards around the exact point the blast landed, so no two breaks look alike, and those shards can be shattered again. Whatever comes out too small is left behind as glowing dust. Triangles, squares, polygons and circles arrive in two materials, neon and metal — and metal only listens to some of your blasts.

FIVE MODIFIERS THAT BEND THE RULES
• Pressure — a plain outward blast.
• Implosion — pulls everything inward, then a small pop.
• Magnet — only metal shapes react, but hard.
• Gravity well — leaves a decaying attractor behind that keeps working after the flash is gone.
• Chain spark — arcs jump from shape to shape along the nearest neighbours.

SCORE THE PILE-UP
You score for every shape a blast actually moves, plus a bonus for each one that breaks. Shapes then thrown into each other keep a combo alive: every collision extends the window and pushes the multiplier up to four times, so a well-aimed release keeps paying out long after the flash. Positioning the cloud beats charging it to the brim.

MADE TO BE PICKED UP
• One finger, no tutorial to sit through, a run starts a second after launch.
• Six neon palettes — Cyberpunk, Vaporwave, Acid, Mono, Ember, Arctic — switchable mid-run.
• A best score for every environment, so all four are worth going back to.
• Three quality levels for the bloom pipeline, so older devices stay smooth.
• Haptics scaled to the size of the blast, plus synthesized sound; both switchable.

NO STRINGS
