I've never pitched a game to someone with a prototype, but I'd imagine Macbat 64 isn't far off from what publishers would have seen when looking at prototypes for Banjo-Kazooie and Donkey Kong 64.
That is to say, bite-sized levels that get the point across of what the final product would be like. Which considering Macbat 64's price tag, isn't the end of the world or my wallet.
