I wasn't sure about submitting this one at first but when I saw the high score episode 9 got, I figured I should.
About the size. The problem is that I use one recording for each scene and each episode has about 5-7 scenes. Also, you'll notice that the episodes are a lot longer than they used to. It causes sync problems and I have to use a different sound format which tends to take up more space. At times, you'll here the same sound get repeated, that is usually when I have the sound re-sync to normal.
