Build a star system, one planet at a time. Every orbit earns you money, and every planet adds mass your star cannot hold. Detonate it, spend what the blast leaves behind, and begin again on a bigger star.

SteamAbout Slay the Stars
Build a solar system. Push it beyond its limits. Make the star explode.
Start with a single star and one planet orbiting around it. Every completed orbit earns you Year Score, which you can spend to expand your system with new planets, asteroid belts, comets, and other celestial bodies.
Click on orbiting planets to give them a temporary burst of speed and complete their years faster. As your system grows, keeping up with multiple moving objects becomes increasingly chaotic and rewarding.
Every object you add also increases the total mass of your solar system, slowly filling the Supernova Bar.
Once your star reaches critical mass, trigger the supernova.
Watch as the star pulls the entire system inward and destroys everything you have built in one massive explosion. In return, earn Supernova Points that can be spent on permanent upgrades in the Skill Tree.
Then start again with a new star.
Build faster. Create larger systems. Unlock new celestial objects. Push your star further with every run.
Grow the system.
Feed the star.
Trigger the supernova.
Repeat.
