Kitty Kat Nap is an endless runner game designed for children. I designed the graphic elements in the game and also contributed towards general concept development, level design and user flow. It can be found here on the app store.
In the game you play a cat that has fallen asleep. You must then navigate through three worlds as the cats dream quickly turns into a nightmare! Below are the landscapes designed for each of the three levels of the game.
Here is some of the character development and sprite sheets.
Here is a video showing the gameplay.
