About this game

Space Crash Simulator is the first mobile app with Smoothed Particle Hydrodynamics (SPH) for planetary collisions. Watch as planets collide and break apart in real time, with a robust simulation running a decent number of particles for a detailed, physics-based simulation..

The simulation lets you jump straight into high-energy collisions or customize initial conditions in Setup Mode. Adjust parameters like particle count, planet velocity, and collision accuracy to create your own collision scenarios.

SPH simulations are notoriously resource intensive but settings like particle count, accuracy and timescale can be adjusted to allow even weaker devices to run it.

it's a great game, I feel like you should a a simulate mode though. Because on some devices, the game isn't fun with all of the lag, and it would be nice to be able to make large sims and watch them in a higher fps then 4. If its not possible then that's fine, and please, if you even read this. fix where the main planet just ignites into flames when you start the sim.

it has got some really good simulations but I t would be 5 stars if it was more optimized and the fact that the trail is on the center of mass so it could be outside or nowhere near the planet. anyways here are some suggestions, a custom mode where you can place your own objects, a rendering mode where you can render 50k+ particle simulations. and also a layers system where different layers have different densities and looks. that's all from me, hope you improve it!

it's not that bad for a mobile game, the performance might need a few improvements, plus I find it weird that the planets that I spawn implode at the beginning of each simulation which doesn't make the collision look as good as expected

What’s new

- Fixed protoplanetary disk textures bug
- Added an option to use your own images as planet textures. Scroll through the planet textures and after Pluto you will now find a "Custom" texture. Click on the blue text and you will be able to select your own image.
- Fixed a touch control bug in setup
- Updated native libraries to support Android 15 and 16 KB memory page size.
- Unity security fix
