Great game… but

The only issue I have with this game is the fact that there is no save button. Until that gets added I don’t see the point of playing sadly.

Help

Can someone comment on how you save the solar system that you created so that if you close the app you can get to it again?

pls add more things

you need to add orbit tilts and so you can save your solar system and make it so you make the planets farther from the sun and I want to rename the sun you need more textures and you need to update the limit of moons so I can replicate the solar system properly and I NEED asteroid moons and a save button and I want to customize the rings for the planets and I want it so you can make the planets smaller than 10

Good but

I really want to add a save file so I can continue making planets and editing them instead of starting over every time

FAQ

What can I do in Planet Builder?

In Planet Builder, you can act as an architect for your own solar system. You can construct planets and moons, defining their names, sizes, orbital speeds, spin speeds, tilts, rings, orbital distances, and visual appearances. The app allows you to observe these celestial bodies orbiting in real-time 3D, complete with trails.

Are there any interactive events or challenges?

Yes, the app includes interactive elements to make your solar system more dynamic. You can trigger an asteroid attack to see planets knocked out of orbit, or use the Asteroid Cannon to shoot asteroids yourself. You can also transform the sun into a supernova that becomes a black hole, which then pulls in all nearby planets.

Does the app offer any pre-made solar systems?

Yes, Planet Builder includes a Quick Start mode. This mode allows you to enter a pre-configured Solar System that includes all eight planets (plus Pluto) and their major moons, as well as the asteroid belt. This mode features high-resolution textures and realistic imagery, such as recent pictures of Pluto from the New Horizons probe.

Can I adjust the gravity in the solar system?

The app provides options to control gravity. You can increase or decrease the sun's gravity. Additionally, you can activate Planetary Gravity, which grants each individual planet its own gravitational field, adding another layer of realism and complexity to your simulated solar system.
