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.

I love the everything about this game, I get to do some form of space crashes when im going on trips for when I can't play spacesim on my computer. the reason its not 5 stars is that it has lots of ads.

good but make a 2d mode because not all phones, even if it's good, can run a 3d spacesim game, make 2d mode so the particle could be raised without getting any lag, and second so we can see how the inside acts with collision, btw add to so when I try to make ring or moon via collision it's not just fricking merge, like add custom orbit or make we can curve the arrow two star

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.
