Jelly Boy SEGA walkthrough - the best and hard game of "SEGA"

Jelly Boy is a 1995 Europe-exclusive action platformer video game developed by Probe Software and published by Ocean Software for the Super Nintendo Entertainment System and Nintendo Game Boy. 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 (at 100 notes) as well as a one-hit shield (after a collision, the notes are lost, and further collisions result in death).
