not sure where to start/stop the timer, so here's what I did:

Start - when selecting the first level End - When you click "next level/menu" after the final ball is dropped.

feel free to change it if my timing is wrong

mod note: hey, finally got too making the rules, timing starts upon selecting the first level, timing ends upon the first indication of the last level being completed 2:30 gg
