I did a lot of messing up.... level 11 can be way faster if you do the skip but it's too inconsistent to waste time on..... level 9 although it seems fast was actually quite slow, you can get around 2.5s faster if you have a better start and bounce directly into the hole (GL WITH THAT :)

Level 1: 9.66 Level 2: 6.84 Level 3: 6.18 Level 4: 9.96 Level 5: 10.29 Level 6: (bonus) Level 7: 16.99 Level 8: 9.78 Level 9: 18.19 Level 10: 17.35 Level 11: 16.84 Level 12: 21.23 Total 143.31 / 2m23s310ms
