LIFTOFF

Bolt your rocket together part by part, then fly it with a single button.

Every piece you place is real physics. Tanks add fuel — and weight. An engine with anything under it can't fire. Extra columns catch the air, so cap them with nose cones. Bolt the thrust off-center and the whole ship arcs over and tumbles, unless you pay for fins to hold it straight.

In the air it's one button: HOLD to burn, RELEASE to cool. Push the throttle in thick air and the hull overheats until it tears apart — but throttle back too early and you'll never make it. When a stage burns out, press again fast for a PERFECT SEPARATION and a burst of speed as the spent stage tumbles away behind you.

Every flight pays out by altitude, so failures still fund the next build. Take contracts, buy engines, unlock decouplers, and climb past the clouds, past the Karman line, all the way to LOW ORBIT at 150 km.

FEATURES

• Grid-based rocket assembly — you decide what goes where

• Real consequences: thrust-to-weight, drag, off-center thrust, staging

• One-button flight: burn, cool, separate

• 15 contracts, 5 engine types, 3-stage builds

• Hand-drawn retro space-poster art, all-synth adaptive soundtrack

CONTROLS: HOLD (tap / left mouse / Space) to burn. Release to cool. When the engine dies, press again fast to separate the stage.
