2D physics-based universe and spaceflight simulator.

This is very early version of game.

Wiki - controls, saves, how it works, physics, planned features.

Github - source code

For now there are 2 game modes:

Main game:

• display bodies
• display vessels
• much higher warp than in editor
• no body collisions
• cannot change body orbit, data, delete, insert
• can load game or map and convert it to game
• maps can be loaded from editor list of maps as new game

Editor:

• insert bodies
• edit orbits
• edit body data (mass, density...)
• change simulation config
• remove bodies
• has collisions
• can load map or game and save as map or game

Other features:

• Try hitting edge of screen with mouse while dragging map
• F2 works as rename shortcut in menus
• Double click on editable text selects it
• Values can be written with SI prefixes (ex. 1.5k for 1500)

Note: Maps are not same as saved game. Map contains only body data. Saved game contains body and vessel data.

It might take some time for game to start in first run (5-20s).
