I have listened to this once, and I am listening again. Since it started playing the first time, I have not stopped smiling (read: grinning like a dope from ear to ear).
Your girl voices are amusing, Chef Pierre is fantastic, Gary is an incredible dork and the mixing of it all is quite awesome. If I were to remark on anything to work on, it'd be putting more emotion into your Gary voice; you get stuck in maintaining that scratchy, med-high voice and, while it's very good, some of the lines come off as dull. I think working on that would ultimately improve the panic scene that people are remarking on.
But that aside, again, I have to say this was fantastic to listen to, a real treat. Kudos on a job well done! ^^
...and yeah, it's been said, but the artwork is also incredibly awesome. Because you are made of win. Ask, you say? Ok! Please draw me something! o^^o Pweeease?
