About This Game

In Grand Space Game you take control of a custom planet with only a gravity well to guide it as well as a limited ability to slow time for close calls.

Customize Your Planet

Many variables to tweak allow you to fine tune a planet to your liking, with familiar presets if you want a good base to start from. As you play, you'll also find yourself discovering more classes of space object to create and play as, providing different play styles and shifts down to the physics. 

Smash Through The Galaxy

You'll go up against many enemies over the course of a run. These enemies will explode into clouds of dust that can be used to form rocks and planets to fling at others. 

Grow Your Galaxy

The earnings from your runs can be used to buy space objects off a rotating shop. These can be placed into systems and balanced into orbits for your own custom galaxy. Systems built can then be used to apply modifiers to future runs, with every object providing unique shifts to the balance.
