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
