Yeah, this is a nice little arcade game (despite the hefty loading screen!) - It felt pretty smooth and pretty intuitive. I think there might be a bug insofar as when you start a new game it doesn't reset the old score; instead, it seems to just subtract 15 from it (at least on Medium mode it did). But perhaps it's just taking the "Legacy Game" diversifier on board and letting your score roll on from the last time :)
