Landolt Ring World is an area accessible from the Hospital.

Features

This area is a small, looping environment where Landolt rings are arranged around the place, with one of them leading back to the Hospital upon interaction. A grid also fills the foreground.

When you first enter this area, the screen will only cover half of your sight. The visible area can be toggled by interacting with the spoon switch. Equipping the Eyeball Bomb effect will give you a full view of the area. Interacting with the Landolt ring directly below the spoon with the Glasses effect will send you back to the Hospital.

The Landolt rings react to several effects:

Child, Glasses, and Stretch will change their sizes accordingly. Interacting with the rings will change their orientation.
Fairy will make them rotate, and using the effect will speed up their rotation.
Marginal will make the rings pulsate, and interacting with them will show a peephole with what appears to be a hot air balloon at the end of it as an ECG sound plays. This peephole is reminiscent of the autorefractor test, also known as the "hot air balloon test" where this image is commonly used in said test to measure eye focusing power.

After clearing the autorefractor test, you will see a yellow hot-air balloon taking you to Sauna Corridors.
