Meh
I've seen the idea done before - I guess the new feature you bring to the idea is the roll bit... but I didn't really think that adds much to the concept.
The music is good and the art is fine - I thought the background looked cool.
I have to wonder how much skill is involved in this - a lot of it on the faster parts of the game is guessing which way you have to turn and hoping you get there quick enough. I'm not sure if you've worked out a way for it always to be possible to progress (assuming you've been playing fast enough and well enough), if you have well done, if not that might be something to work on.
All in all it's quite a plesant time-waster - but it doesn't bring much to the table in terms of originality, in my opinion.
