Turn right and jump onto the treacherous platform to reach a pillar. From here, go up the platforms on the left. Be careful, because on the second there is a Dark Dantini that will attack you and at the moment you will not have any crystals. Try to jump to the side. You will come to another pillar. When you get on it, it will start moving. Grab the crystals that are along the way, but be ready to jump, to avoid the attacks of another Dark Dantini who is on a platform next to it. At the end of the path the pillar will begin to shrink. Jump on the precarious platforms and climb them until you reach the entrance.
Quickly go through the pillars in front of you, which shrink when you jump on them and avoid the attacks of the two Dark Dantini on the sides. You will come to a platform with three crystals. Go up the ladder and get more crystals. You will then have to jump to other shrinking pillars while avoiding the swinging spiky balls. So move with timing. Collect some more crystals and reach the door. Go in.
Here, as in level 4.3, you will have to push the balloon in front of one of the two doors and then repeatedly jump on the pump until it explodes, to open your way. The choice is completely free and the two paths then rejoin, however it is advisable to open the door on the right. If you choose the door on the left in fact, you will meet Platfotm Pete again and you will have to overcome an extremely tricky path. You will have to move from one pillar to another, jumping over three platforms similar to those you have already seen in level 4.6. The platforms flip over every few moments, alternating, so you'll have to jump with the utmost precision and timing. You will have to repeat the process three times to reach the door. If you choose the door on the right instead, you will have to deal with the less dangerous Ballistic Meg. Follow the path until you reach the door, keeping close to the edge to avoid the flames in the center. There is only one slightly treacherous point, where you will have to cross a narrow bridge. Do this when Meg is not around. Along one side of the path you will also find some crystals.
Whatever path you have chosen, after crossing the door you will arrive in this area. You will have to continue on some pillars. Some of them move sideways and others begin to shrink as soon as you step on them. So be careful. Along the way you will find crystals, but also Dark Dantini that will attack you. Eventually, after a last disappearing pillar, you will find the exit gong.
