Jelly Boy puts the player in the control of a jelly baby with morphing powers. His quest is to find various items inside a factory so that the elevator doorman will allow him to meet the person in charge. The most important items are musical notes, which serve both as an extra life as well as a one-hit shield.
In 1995, Total! ranked Jelly Boy 73rd on their Top 100SNES Games writing: "On the surface this platformer seemsbasic but the challenge is big and it’s strangely gripping."
