It was pretty good.
Here's why...
Graphics - Well, there are good graphics. There all over the flash. Though, they weren't good enough.
Style - Okay, this was good enough. Too good, actually. The way the hearts were animated was quite amazing.
Sound - Okay, no charcter really talk because they're, of course, animals. The music was a good song for a Japanese song. What was that song anyways?
Violence - There were no violence.
Humor - Okay, it was funny enough that the bunny was in love with the cat and told her that they don't belong. How the bunny suddenly appeared in the elevator was also humourous.
