Nice, very nice.
I liked everything about this game, from the attitude of the protagonist to the overall level design and controls. It would be nice if the main character could jump higher.
Also, the artwork of the characters could use a little touch up. I like the anime style, it just need a little more detail. Overall, nice game, just don't do what a lot of people on newgrounds have done and make one awesome game, promise a sequel and never deliver.
