Great! Just great!
I waited until seeing all six episodes (or seven if I count each half of this two-parter separately) before writing a review, and all I can say in summation is great! Just great!
Your comedic timing has really developed since the first episode. Your writing has always been good (regardless of what you think of it), and has gotten even better. You have an amazing flair for creating monsters that are funny and creepy at the same time. Obviously you know quite a bit about anatomy and weird zoological specimens (including housefly mouthparts and Surinam toads... YUCK!) Your character designs are first rate.
If I have any negative criticism at all (and I don't really, but I've seen where someone else mentioned this and I agree) it has to do with your preload. You need a status bar, a start button (on which the frame should freeze after fully loading), and a replay button at the end. At one point I had to check something in the kitchen while an episode loaded. I didn't know how long to expect it to take, it started automatically while I was fussing with dinner, and since there was no replay button at the end I had to reload the whole thing while I sat here watching the screen. But that's technical stuff. It doesn't affect the quality of the 'toons themselves, which is first rate.
You're excellent at this. Personally, I liked this last, more story-driven episode. Not everything has to be a laff-a-second. I've even tried doing drama in Flash, but I can't say I've been successful at it yet. Flash seems to lend itself better to comedy or surrealism than to serious storytelling, but that's an inherent limitation of the style the software produces. I thought you handled it well.
Your funniest moments, however, definitely involved the adorable little Lovecraftian horror: "I love you." About him, I probably agree with the mainstream. I was literally laughing out loud during parts of that episode.
Excellent! 10/10
