The Invisible Maze (宇宙迷路, Uchū Meiro, Space Maze) is a combination of different themed locations you must travel through in order to get the Invisible effect. It is accessible from the Bowling Zone.
Features
When you first enter, you will be transported to a dark area with a yellow and purple tree-like object in the middle. You can either use the Penguin effect to go straight to it, or you can simply cycle upwards, which will teleport you to different sides of the screen, but you will eventually get to it. When you interact with the tree, you will be teleported to an outlook with a girl standing on her own. If you use the
Chainsaw effect on her, the scene will darken. When you travel downwards from the tree and go back to where you first entered, you will be transported to a monochrome area with Yukata. Here you have to travel in the direction he is facing for a short while until you are transported to a new area similar to Yukata's. From here, you can interact with the purple silhouette of Urotsuki to get the Invisible
effect.
After you have the effect, you can travel back down to Yukata and a small wormhole will be there. This takes you back to the beginning of the Bowling Zone.
