Castlevania: The Adventure/Stage 3: Dungeon

Stage walkthrough
Those spikes on the ceiling are there for a reason: soon they will start lowering. Christopher has to destroy a screw-column, and the ceiling will go back up. Still, there are three subsequent crushing ceilings. Later, spikes come from below, and in a third area they come from behind.

Enemy list:
 * Giant caterpillars
 * Mud men

Secret room
This secret room is easy to identify if you are playing this game on the European or Japanese Konami GB Collection vol.1. There is a "room" that consists of a vertical passage, but actually Christopher can get through the wall.

Boss
The easiest strategy against this flying enemy is to get on the upper ledge and shoot it with the fireballs, but always be ready to hit it with the whip if it gets too close. Therefore, rapid-fire is a bad choice.
