Credits

Credits
Credits represent money, and as such they are the currency of Sustainaville. Credits are necessary for purchasing any Structure in the game.

Generating Credits
Credits can only be gained by successfully helping communities around the world, or by receiving a donation from a friend through Facebook. Credits can also be gained by donating to the Save the Children foundation, with higher donations awarding more credits. More information can be found here.

However, you will start each level with a supply of credits, so don't fret!
