I don't know why I like this, but I do...
It's an interesting concept, and to realise it's part of a series is somehow encouraging. I like that you've taken something simple and made it unexpected and original.
Animation style is interesting, if not a little plain. Even then, however, it's not necessarily a bad thing.
The music was well used, I think, apart from it jumping slightly.
Voice quality is good, and as an added bonus: amusing.
Good work. Should be interesting to see what's next. :P
