Good!
I laughed about every time the racer spoke something. Just the imitating of CAaaaaRRRRRrrrRRRR...NOISEES! made me laughing, even when the jokes themselves weren't extremely funny (sorry). Some of them were, though.
I have nothing to complain about art+animation, and the voice acting was superb. This definitely deserves the max points. Keep up the good work!
