Like others have said, this is a great example of a prototype. Once you understand how to cheese it, it's easy to try and max out your size - but, then, you realize that there is a limit, and it's the number of contracts you can take. You hit a point where you're clicking next and taking contracts just hoping for the belly to get bigger, but it's kinda luck-based. Was disappointing to realize I wouldn't actually figure out how big the belly could get, lol.
Still: fun and simple project that has a well-designed model.
