About this game

Particle Physics Simulator offers a physics sandbox with n-body capabilities where the behaviour of the system is driven by each particle's gravity. Adjust the gravity strength, the number of particles, the friction or the collision policy.
Set your initial conditions and just watch the system evolve or intervene to decide the fate of the particles!

Features:
- N-body physics simulation with pure gravitational interactions between particles.
- Create walls particles can't trespass. Watch them bounce off.
- Collision policies: physically realistic elastic collisions, mergers or no collisions at all.
- Configurable particle colorus.
- Configurable background image/colour.
- Configurable gravity strength.
- Configurable particle masses and sizes.
- Add friction to the mix!
- Accelerometer support.
- Repulsive forces.
- Shoot particles of different sizes.
- Repulsive particles.
- Static particles.
- Simulation area: screen or big area with panning and zooming.
- Enable or disable the central black hole which exerts a neat attractive force towards the center.
-Enable or disable particle trails (disable to improve performance).
-Modify simulation velocity in real time.
-Particle-Particle and Particle-Mesh simulation methods. Use first for accuracy, use second for performance.
-Display grid densities as background in Particle-Mesh method.

Good game though i feel like the map is so small and i want a map that you can zoom out or in move around and probably don't make it so when a certain amount of particles go in each other they somehow form a black hole and it is just annoying

when the star reaches the center of the black hole It immediately/randomly crashes... please fix it.... my phone is not outdated but the game crashes....my phone is a Infinix smart 8...

Cool app but the settings button [...] often locks up after the initial use and you have to exit the app to adjust settings.

What’s new

Add margins to bottom buttons, zoom-pan layout, velocity slider, and FPS text info. This prevents invisible buttons on some devices due to the navigation buttons occluding them.
