Some might call the animation and style old and outdated, but to me it's just classic, and classic done really really well.
The only thing really lacking is the voicing. I mean, I'm fine with all the anthropomorphic creatures sounding completely human, but the audio quality isn't the greatest and could do with some mixing to make it sound more real and fitting for the various situations. Not the best voice actors either. Some background SFX would be nice too, doesn't really feel like much of a party when there's no background chatter, and it just feels really naked in general when there's no background noise outside, like birds or cars driving by, or anything of the sorts really.
