FEATURES

Why Players Love It

Real Physics Engine

Every orbit follows Newton's law of gravitation. N-body simulation with no shortcuts, no cheats — real gravity.

100+ Handcrafted Levels

12 chapters across volcanic worlds, frozen expanses, imperial fortresses, and the event horizon of a black hole.

Story-Driven Campaign

Meet NAV, Captain Vex, Kira Frost, and a galaxy of characters. Every chapter deepens the mystery of why you're here.

STEM Learning

Kepler's laws, gravitational slingshots, escape velocity — learn real orbital mechanics through play.

6 Unique Worlds

Volcanic hellscapes, ice fields, nebulae, imperial sectors, and things darker still. Each with a unique atmosphere.

No Ads. Ever.

40 free levels across 4 chapters. Premium chapters $1.99 each, or unlock everything for $9.99. That's it.

THE STORY

Lost Among the Stars

"You wake up. Stars you don't recognize. A ship held together by luck. And NAV — your ship's AI — running on backup power."

You are Rip Largo. Ex-Earth Space Agency operative. Your last mission went wrong — catastrophically. Now you're galaxies from home with nothing but your wits, a damaged ship, and one objective:

Find Earth.

Earn allies. Outsmart enemies. Fling planets, slingshot through binary star systems, and destroy anything that stands between you and home.

NAV TERMINAL v2.1

NAV: "Good morning, Largo. I have good news and bad news. Good news: we're alive. Bad news: I have no idea where we are. Shall we find out?"

EDUCATION

Learn Real Orbital Mechanics

Every level in Rip Largo is a real n-body physics simulation. Planets orbit according to Newton's law of universal gravitation. No approximations. No faking it.

Gravitational Slingshots

Use a planet's gravity to change your trajectory — just like NASA's Voyager missions.

Stable Orbits

Find the Goldilocks zone where gravitational pull equals centripetal force.

Kepler's Laws

Discover why inner planets orbit faster and orbits are elliptical, not circular.

Escape Velocity

Calculate the speed needed to break free from a star's gravitational pull.

Binary Star Systems

Navigate the complex gravitational dance of two stars orbiting each other.

N-Body Physics

Experience the chaotic beauty of multiple gravitational bodies interacting simultaneously.

Recommended for ages 9+. Perfect for curious minds, science classrooms, and space enthusiasts.
