Level skip:
Enter a "Royal Palace" room at the end of a level, where the bombs may be collected. Take one bomb, then find the bomb that will explode. Collect all the other bombs, and take the lit bomb last and leave the room. Game play will resume at the next "Royal Palace" room.

Bonus points:
Collect all the lit bombs in a "Royal Palace" room in order to collect a 50,000 point bonus.
