The Rabbit and the Owl is a single-player or two-player co-op puzzle-platformer which introduces a negative space landscape. The titular characters exist in opposite worlds of light and dark and are only able to progress by helping each other. Gameplay emphasizes solving puzzles which are composed of various mechanics that shift the environment and thus affect both characters in different ways.
I was working on an image effect for rounding the edges of the platforms. It was implemented using a separable gaussian blur filter, and then applying a threshold.
