Polyion is a world management game.
Your job is to collect resources, place buildings and earn money to grow and build your world further. Maintain a steady flow of resources and finances and population sentiment so that your world can thrive.

The game is being re-released into 0.1 Early Access so while there is still a bit to do in the game from world building and maintaining your population sentiment and resources, there is still a lot that needs to be added and updated so there are many buildings and features yet to be implemented and there may be issues or bugs within some of the games features.
Harvest resources from the world, place buildings that bring in money and resources and maintain a good sentiment with your population. Placing buildings that your population does not want (i.e. overcrowding your world with one type of building) could cause them to become unhappy and leave your world. With no people in your world working or providing taxes could cause you to lose money and buildings will not provide resources or money if no humans are working.
You can harvest wood, stone and metal from the trees and rocks in the world.
Other resources such as money, power and water will be gained from placing buildings and maintaining them and keeping your population sentiment high. You will also receive money from taxes and humans working.
There is no winning or losing and there is no way to lose the game, and while you can recover from a major loss of resources or population, once you lose enough people or resources it is basically impossible to recover and you will most likely have to restart.
