Thanks for the feedback! I agree with your critique--I think we're happy to have gotten anything solid done given the time constraints, but it'd be nice to tweak the difficulty (and I suppose sprite collisions with water/etc?) to adjust the gameplay. Perhaps, as you say, starting with fewer enemies as an easing in. I also thought that maybe the sprites maybe move more slowly at first (say, on every other beat), and then the speed and tempo ramp up as you go farther. Could be a little Tetris-y that way.
