Bomber Mansion
In order to get the Bomber Mansion you must use your
bombs to kill yourself or die from one of the enemies. The professor
will say something about training in the Bomber Mansion. Select
"No" when asked to continue, and on the main screen
you will be able to use the Bomber Mansion to train. The Bomber
Mansion is a training place, and when you complete all five levels
you will receive a rank. Your score determines your rank. Your
score will go down if you lost a heart (you can find them hidden
in blocks) or if you place a useless bomb (a bomb that does not
explode or kill anything).
Planet Bomber world
