What’s New Version 0.52
NEW: Planetary rings! Give any planet a ring in Setup Mode: tilt it, resize it, watch it orbit, catch the planet's shadow, and rain glowing debris onto the surface. Or shred a moon into a ring with the tidal break-up action.
- New "Extra" menu in setup (rings & Roche orbits)
- Graphics and game mechanic improvements
Keep the ideas coming!
Description
Smash worlds together and watch them shatter, merge, and melt, driven by real physics, not pre-made animations. Every planet is made of thousands of interacting particles, so every collision is computed live and no two impacts ever look the same.
Build your own scenario in Setup Mode: place up to 8 bodies, set their size, density, spin and velocity, then let gravity do the rest. Or dive straight into a head-on collision and watch the debris glow, cool, and form a crust.
- True particle physics (SPH), the first of its kind on mobile
- Molten impact zones: heat, lava, and cooling crusts
- Give planets rings or shred a moon into one with tidal forces (Roche limit)
- Protoplanetary disk and colliding-galaxies modes
- Black holes that tear planets apart
- Custom planet textures from your own photos
- Runs on everything: tune particle count, accuracy, and timescale to your device

Build 887373772v0.392026-06-24 19:54:06
- Added real time lighting: planets have night and day sides, and cast shadows on each other
- You can now make planets much bigger by increasing their particle counts.
- Removed 2- and 3- body mode and replaced it with "Planetary Mode". In this mode you can add up to 8 planets in a scenario.
- You can now stand on the planet's surfaces. But beware, it's like standing on pingpong balls :-D

- Added Mercury, Saturn, Yellow Star and Blue Star textures
- Replaced the "Texture" selector by a "Material" selector, you can now set all planet materials with it, but also a black hole (single particle with much higher mass) and the new glowing star materials
- Added "Spin" controls to make planets spin at a a velocity and direction of your choice. If you make them spin too hard they'll fly apart however.
- Fixed overlapping UI

- Other bug fixes
Build 873189098v0.152025-03-12 22:26:18
- The GPU readbacks will now reduce when fps is down. That should give you more control when simulating with higher particle counts. The remaining stutters are due to the heaviness of the computations and unavoidable.
