Always aim for the bottom platform within a given gap as you jump. Landing on the lower platform lets you skate forward unharmed. Avoid bumping your head for being too ambitious with a jump spell at the end of your run. A low jump usually appears just after completing a high jump, so be ready for that trap and tap the screen more softly if you need to in order to avoid bumping your head. Additionally, you should give yourself every possible advantage by making sure to make precise taps using your left thumb (since you may have to obscure your field of vision if you use your right thumb).
