Prototype of a physics-driven space sandbox game. Create stars and planets, watch them interact, beware of alien wars and use the gravity.

What and why

I created this project long time ago, hackathon style, without any engines, architecture or a plan for a gameplay. It was fun to make such thing with only simple shapes, Canvas class and a couple of random formulas.

How to play

• press to create a celestial body
• longpress to create a larger body
• move when longpressing to add initial velocity
• pinch to zoom
• two-finger drag to pan the universe
• tilt your phone to change the gravity

The universe

• each body has a name displayed when zoomed in
• there are special bodies to discover
• bodies pull other bodies
• bodies vanish outside the universe
• large bodies explode
• large explosions create black holes
• black holes suck other things inside and grow
• bodies spawn aliens
• aliens shoot enemy aliens
• bodies explode when hit by a laser
