A state of confusion arises when we cannot clearly define what we are looking at. The game uses this phenomenon to challenge your visual perception, making you analyse what you’re seeing. These blog posts are about negative space and composite shapes that are used in Ravioli to cause confusion.
NEGATIVE SPACE. What do you see? A green octagon or a black octagon?
There are a couple of features of the game that are designed to cause confusion. One of these is the use of negative space, i.e. an absence or something that isn’t there. Instead of seeing solid shapes, you’re looking at spaces created by shapes being removed. This causes confusion as your brain is trained to look for what is there, not what isn’t there. So the answer is you’re seeing a green octagon stencil on a black base.
