I didn't think this was the best of these entries, but it was certainly interesting. I thought it did go on a bit too long. It just seemed like something that wasn't that complicated. It was pretty fun to watch, seeing as how you didn't know what was going to happen next. Dang those perpetual motion machines! The voices were pretty spot on.
The other entries in this contest that I've seen were more creepy. This was a lot more comedic. I guess it does have a bit of a creepy atmosphere because it ends on such a weird note. Those kids love guns and violence! For the most part, this is a well done cartoon.
