This is actually one of the game's hardest zones. To get past act 1, you must
know how to use the hang glider. Run into it at full speed and keep pressing
down/left on the direction pad and, after a lot of practice, you will make it
over the chasm. Act 2 is very nasty too. If you can, take the path through the
clouds and avoid the section where you have to hang glide with spikes on the
floor AND ceiling. The lightning cannot hurt you, though.
