Game Guide

In Jelly Boy (Europe) (Proto), mastering the control of Jelly Boy is crucial. First, understand that Jelly Boy's main ability is to bounce. Use the directional buttons on your SEGA controller to move him left or right. When you press the jump button, Jelly Boy will bounce into the air. You can use this bouncing ability to reach higher platforms or to avoid enemies. To defeat enemies, you can bounce on top of them. However, be careful as some enemies might require multiple bounces to be defeated. In some levels, there are special items that can give Jelly Boy extra abilities. For example, there might be a power - up that allows him to bounce higher or to shoot projectiles. Keep an eye out for these items as they can be very useful in difficult levels. When facing puzzles, take your time to observe the environment. Some puzzles might involve moving blocks or activating switches. You may need to bounce on certain platforms in a specific order to solve them. Also, be aware of the time limit in some levels. If you run out of time, you'll lose a life. Try to complete the levels as quickly as possible while still solving the puzzles correctly. When exploring a level, don't forget to check hidden areas. There could be extra lives, power - ups, or collectibles in these spots.
