'Galaxy Clicker' is a 2D Incremental Game for PC.
The universe started not with the Big Bang, but with clicks. In Galaxy Clicker, the player gives shape to the countless stars and systems in the universe by clicking. Clicking the empty void of space awards the player cosmic power.
Cosmic power can be used to create Stars. After creating stars, players may create planets to form a system. By creating many systems, players can then form galaxies. And then various galaxies form galaxy clusters, and so on.
When enough galaxies have been created, the option to create the stars as red or white dwarfs is unlocked, letting the player make other types of systems. Asteroid belts and the like are also included.
Players can also unlock star helpers with their cosmic power that automate the collection of cosmic dust. More helps is more dust, more dust is a bigger universe!
Educational and hopelessly addictive at the same time, the player will eventually create an universe maybe bigger than our own.
