Meh.
For one reason or another, the jokes in this flash seem like really flat spin-offs of the earlier ones. You could have just said it was a remake and let it be, but now it just seems kind of lame. If this wasn't an attempt to remake the Pancake Doomsday episode, then I'm calling idea squandering. It felt like you wasted alot of new ideas by making this episode.
The intro was great until it came to the re-used audio of the pilot, which only makes me feel like this series is growing stale. The pinch harmonic when the ass joke was played felt tacked-on, and kinda smeared it. The cocaine idea is seriously overused. I expected something better than that. If you really had to use it, you could have expanded on the idea.
The only thing left I can give advice to is the facial expressions. The one of Satan just flopping his tongue while having a sort of pinched mouth was hilarious, It actually made me keep watching. Please, just take your time making these. I would rather have 2 hilarious episodes than 5 only chuckle-worthy, 3 minute episodes. I'm looking forward to your next episode, don't fail me meow.
