310 points! :D Not bad, if I do say so myself.
I like the music, but even a small step sound could have added lots.
And the concept is one of if not the strongest aspects of the game - this is a solid idea..!
My biggest gripe is the occassional softlock. You get a combo that's impossible to achieve.
I rate the game 3 Dwaynes out of 5 Rocks.
