I played through the demo. I would have to say its pretty good. My only beef is its 800 points. It feels kiddied up (can't remember if the original was a true arcade or console sequel - gonna check my PC emulators later today) but the gameplay remains solid with larger, colorful screens and more obstacles.
At 400 points I would have bought it without thinking twice, unfortunately at 800 points.... there's better games out there at that price. Its worth checking out though if you're a fan of the genre.
