Your hero Harley has shrunk himself to the size of a mars bar and you must help him on his mission to uncover each of the components needed to rebuild his destroyed shrinking machine so that he can return himself to full size once again. In the amazing Harley's Humongous Adventure you must explore the environment in Harley's cool green suit and use items like marbles and rubber bands to help you fight off enemies and complete your mission!

For those into other brilliantly cool titles from this action packed genre we recommend that you try Salamander, Kid Icarus - Angel Land Story and the fantastic Super Mario Land 2 - 6 Golden Coins!
