I really like this game, but Imma just say two things anyways that are kinda negitive to the game its self.
1. the songs are not in a order of difficulty on the menu, but that's not too bad to be fair.
2. The last song is way to difficult to do, mainly due to: The jump key isn't the best at all times, it goes way too fast for its own good, its fair to say that it would be impossible without the only one of the two modifiers that help you as far as I'm aware of.
That's all I got. overall on a scale of 1 - 10, id say this is a 9, and personally, I suggest anyone to play this, but then again this is subject to bias, I like my low pixel rates.
