In the Suspense level, there is a way to move closer to the ending. To do this, enter in the code (2781FF) or just travel through the level until you reach this code. Upon entering the code, jump straight up into the 'moving floor' room above you. In the room, walk down into the path of the first moving floor and start shooting into the floor to keep your place. Now, when the floor covers you over, begin pushing the joy pad diagonally left/down and forward, until you're pushed into the room's left wall. If you succeed in getting into the wall, start pressing the joy pad forward and down. If you don't get accidently trapped in the wall, you will then be dropped into another room closer to the end of the game.
