Cream and Cheese in Sonic the Hedgehog isn't an officially released Sega Genesis game. It's likely a fan-made ROM hack or a title that exists only as a prototype or concept.  Without official details from Sega, any description of gameplay or development history would be purely speculative. Information on the game's origins, gameplay, and creators would need to be sourced from fan communities or dedicated ROM hacking forums which focus on Sega Genesis titles. The game's very existence is likely tied to fans' creativity and attempts to modify or create content within the Sonic universe.
