Another book adaptation, this time based on the Green Sky novels by Zilpha Keatley Snyder. Only this game isn't a text game, but rather a combination adventure and action platformer. A large populace live in huge trees (Erdlings) and everyone else lives on or underground (Kindar), this is making people unhappy. Unfortunately, the one person who can bring peace has gone missing and now you get to find him. Take your pick of five different characters of difference ages and backgrounds and then try not to fall off of stuff as you wander about talking to people.
You get a set of adventure game style verbs but you also need to keep track of money, hunger, sleep, and overall health. Losing all your health means being taken back to your home. As you explore you'll increase your spirit which starts to give you special powers like pense which lets you sense emotions from people and animals which gives you more clues. Later on you'll gain the ability to make trees grow branches which will let you access difficult to reach spots and finally the power of teleportation.
You mostly get around by leaping off of platforms and gliding around on a fancy parachute all a shuba which can randomly tear when you take damage so bring a spare. You'll also need tools to cut weeds, food to keep from passing out, and wits because not everyone is your friend and you can even get kidnapped by political enemies. I've never read the books, but this game takes place after them and it's considered canon to the universe.
