if it's any consolation, you boss sounds like someone who just doesn't understand how to properly run a business "guessing hes new since its a new buisness"
you don't THREATEN your worker :D it's a BAD IDEA. When he starts giving you this "you care to much about money" crap, just think that if he was as noble and virtuous, he'd probably be more willing to pay up :)

Don't worry future employers hire people with FINISHED games, start to end. If you didn't finish a project at that place I'd say finish your own projects because one will really stand out and catch their eye. (Rather than just handing them a ton of assets to an incomplete game)
