Jungle Boy is a side-scrolling game featuring 2D retro style graphics. The objective is to walk or run to the right, avoiding nasties and rocks. If you touch any nasties you lose a life, collect as many food as you can.
Spiders fall down from a strand of web before climbing back up and repeat the process, in some situations you will have to jump over a spider than walking under to avoid them.
Nasties move towards you along the ground, your only option is to jump over them or if available jumping onto a cloud.
Rocks will make you trip up, preventing you from running forward or jumping until you are clear of the rock.
