I'm in.

Blue World is a game where you roam the blue square you call home as a yellow circle collecting ovals. You are able to access inaccessible parts of the world by jumping, which turns the square. You must avoid being attacked by the Red, which will kill you if it touches you. It can also turn the world, forcing you to jump. Can you collect all of the ovals? How many can you collect?
