Hi Product Hunters - Here's a new social good game that is a unique twist on endless runners that also supports volunteerism in our national parks. You control two characters at the same time to collaborate across different park terrains to do things park volunteers would typically do: clear trails, greet visitors, clean up the environment, help conserve wildlife and more. The game is free with no in-app purchases. It was developed by Schell Games, produced by Games for Change and funded by American Express to help support volunteerism in our national parks. The American Express Foundation will make a $1 donation to the National Park Foundation for each download of “Save the Park” occurring on or before December 31, 2016, up to $50,000. Thanks and let us know what you think. - Michael
