A billion dollars...
Bruh, that's some serious greed problem right there, if one grinds for candy wrappers that badly – even in a small NSFW videogame. xD
Maybe game should have some bad ending for that case, like if you got over 10 million $ – you get "IRS open up" event at 3 AM. ( -_-)
In that game there's really no sense ever making more.
