Thanks, glad to hear that it feels about right to play, especially since I never actually played the original game, and tried to get a feel for it from YouTube videos. The horizontal speed isn't quite as fast as the original, which means more tapping is required, but I can't tweak that without causing jerky scrolling due to the low resolution.
I was wondering if maybe I made it a bit too easy since I could get a score in the 30's after a bit of practice, but it doesn't sound like I need to worry. Thanks for the feedback.
