Thank you for your kind words! The scrolling being slow is a technical limitation of of my scrolling implementation. Actually most c64 games can't very scroll fast, due to the limitations of the hardware (there are not enough cpu cycles to redraw the whole screen every frame, but the hardware can move the screen over 8 pixels, so if you scroll slow, you have 8 frames to spread out the work). I have some ideas for improving it, but it will probably introduce other artifacts. I think the easiest solution for this game might be to freeze the game until scrolling has caught up.
