Wow, that's kinda really rude.
I personally am enjoying the progression. Maybe it's not coming out fast enough for you, but I'm fairly certain that the people working on this project have lives and jobs besides this that they have to take care of.
If you don't like it or you have constructive criticism to give, that's fine, but you don't have to be such an ass about it. Unless you're out there making your own game, giving people the option of naming their own price, and making sure it's a quality game while cranking out the chapters faster than the production of this one, maybe find something more constructive to say next time, yeah? Considering you can't do it yourself...
