You get +25 points any time you jump using the space bar rather than hopping with the right arrow key. +50 is awarded in addition to this for every flower you clear successfully. So you can earn +25 extra points whenever you are on the left-most pad/rock in a set of 3 pads/rocks by simply tapping the space bar (Note: this is also possible if you are far enough left on a set of 2, but this is trickier to judge). Also if you are going for a HIGH high score, wait on the last rock of any level and collect as many flies/dragonflies, worth +10, as you can before your power bar runs out. Remember to save just +enough power to make that last jump
