This was honestly put together very well, it's a very interesting concept, putting together the Kingdom Hearts universe with the Mario Brothers universe, and I like it.
I do have gripes with this though, grammatical errors really bugged me at times, and emoticons honestly shouldn't be used.
I understand this is a flash animation and what not, but it takes away from the feeling of a true Kingdom Hearts/ Mario Brothers crossover.
This was interesting, and I might tune in to the next part.
