Thanks for the thoughtful comments!
I don't think collecting all the pucks on the main level is possible. On most of the levels, I am not sure what the optimal approach really is. I just wanted to allow for many approaches so players could experiment. Originally I wanted to add a global leaderboard, but I haven't opened that can of worms (yet?).
I think I will revisit that collection sound! Its got to be short and simple because it happens so much. But it could surely be better.
