## Description

Space Crash Simulator brings Smoothed Particle Hydrodynamics (SPH) to planetary collisions on mobile. Watch real-time impacts and fragmentation with a detailed, physics-based particle simulation.

Jump into Setup Mode to customize initial conditions. Adjust particle count, planet velocity, and collision accuracy to create your own collision scenarios. While SPH is resource-intensive, adjustable settings help the simulation run on a range of devices.

## Review summary

Space Crash Simulator is praised for its satisfying collisions, diverse modes, and addictive gameplay, with strong customization options. However, it suffers from lag with many particles, desires more realistic physics and features, occasional galaxy-merge bugs, and several UI gaps. Overall it’s appealing and fun, but needs optimization and deeper realism to reach its full potential.

### Pros

- Satisfying collision physics with visually pleasing particle interactions.
- Four modes (two-body, three-body, proto planetary disc, galaxies) with customizable layouts and textures.
- Fun, engaging, and addictive gameplay that players highly praise.
- Strong potential for expansion through user-generated content and additional astrophysical features.

### Cons

- Lag and performance issues, especially at higher particle counts, with requests for better optimization and smoother FPS.
- Lack of realism and missing physics features (atmospheres, clouds, Roche limit, black holes, neutron stars) across modes.
- Galaxy mode bugs such as galaxies failing to merge, causing a degraded experience.
- Missing UI/placement controls (ability to place/spawn objects, type particle counts, rings orbits) and other quality-of-life features.
