Pauls Hints and Tricks
Hint: More effective battling
When your in the dark world be sure to use the light beam as much as possible. It wipes out enemeys in a flash. Opposite for the light world.
Hint: Blowing open cracks and walls
A good old charge beam doesnt always do the trick to get open those hard to find cracks. Sometimes it takes a little more power then that. Use a few missles and that should finish it off for good.
