Various Gameplay Hints
Don't try and grab all of the critters on your first run, for you can always come back and try again.
Spikes will pop your Dingles, so be careful to avoid them as much as possible.
Watch out for flame spurts. They're not always obvious to begin with, but they can sneak up on you.
