Extra lives:
Jump across the first pond at the first part of level 1-3
and hit a pole. Hold Left as the pole propels your character
upwards back on the pole again. Each time your character is sent
upwards, one extra life is collected. Repeat this process until
ten extra lives have been collected, then locate the next pond.
Repeat this trick again to collect more extra lives. Note: Collecting
more than 255 extra lives will reset the counter to zero.
