To reach 20+ you should think ahead and save apples somewhere, for exapmle - in one corner. Theoretically, with some luck, you can reach any length. Just keep your length <8 so you can fly fast and dont touch apples from "garden" corner. But that is kinda boring.
P.S. Got 22 from 2 hours of playing.
