Yea, the speed is what makes many of the levels satisfying/fun. I was thinking initially that I would offer a score system that used a combination of time and blocks, so getting the right balance would be the purpose here. Ultimately I didn't get around to balancing the scoring in a way I was satisfied with due to time restrictions, and the way the scoreboard works was never really explained. I do think, as you suggested, that if I were to expand on it, splitting the levels with different goals in each would be nice.
