Welcome to Planetastic: the Solar System Sandbox.
Build a solar system stable enough to support life by placing a target number planets in orbit.
The game is currently in early alpha with only the basic physics and planet placement implemented, but you can get it now on Google Play:
The game features multi-body gravitational mechanics so the placement of all planets affect the orbits of all the existing bodies, including the Sun.
The game is built in AGK v1.08 r21 in Tier 1.
Revision 3 of Planetastic is now live on Google Play.
The main addition to revision 3 is the introduction of the Challenge Mode.
In Challenge Mode, you must create a solar system that meets the objectives set for you. The objectives consist of criteria like:
There is no time limit to complete the objectives and no 'game over' so to speak, although some challenges can become impossible to achieve if your design gets out of control.
But, if you manage to meet the challenge, you will see the following screen:
This screen gives an overview of your system before you can either stop playing or try a new challenge.
Revision 3 also sees the following changes:
Next on this horizon is a tutorial mode, the ability to name planets and random events (such as comets and rouge planets).
The whole UI has been rearranged to provide a better experience and the planetary stats that appear when zooming no show directly underneath the planetary name. No real reason for this, other than aesthetics.
Thanks for playing!
