Dr.Green

Having been abandoned by his parents as an infant, the boy known as Dr.Green grows up in the forest to be its guardian. One morning when Dr.Green wakes up he finds the forest under assault by workers cutting down all the trees and capturing the animals.

Dr.Green is a retro-styled platform shooter. You have a gun and a double jump move to rely on as you battle through the eight stages, battling malicious workers and dodging industrial equipment and bottomless pits, finally facing a boss battle at the end of each stage.

Throughout the levels are acorns for extra points, as well as caged animals which will give you back some health if freed. You have three hitpoints as well as a handful of continues, letting you pick up from the beginning of the current level segment.
