Exesiv, 20, requires 1 more energy to obtain max score *as I calculated it* 25, Obtained it, not sure how you wouldn't.. 30 just requires you to take an unnecessary cannon on one of the jumps, 38 requires you to use a start *just to gather energy* 40 just requires a bit of unusual thinking with the starts... *pulling the ones unlocked near the finish, to collect your power-ups* anyone that manages a max on 20 give me a heads-up ;)
