Notable gameplay mechanics: The game was about making the right choices. You were in a place and needed to find the way to a new place. There were often several moves to make, some more ecological/environmentally friendly, some less. It had a limit to how unecological you could be - if you did too much damage to the environment, the game would end. As you damaged the environment, the game's colors got less saturated, eventually turning grayscale before ending the game. Some choices could "heal" some of the damage you caused.

Other details: It was mostly set in nature, one of the tasks was to cross a river and bad choice was to cut down a tree.

Thanks a lot!
