Nice!
Very fluent animation, and a really solid art style. Everything looked very soft, very mutable, and energetic. The backgrounds looked almost as good, although they could have used a bit more detail. The kind of tripping scenes looked good too.
The script was funny - I'll admit I laughed when he jumped through the door to be back in the same room. When it wasn't plain funny like that, it was just strange enough to be entertaining. Solid script.
Good animation, good writing, and solid art. This get's a 4/5 and 8/10. Good work!
