Game Guide

In Mappy (Japan) for FC-NES, your main goal is to catch all the burglars on each level. Start by carefully observing the layout of the stage. Look for hiding places where the burglars might be. Use Mappy's jumping ability to reach higher platforms. When climbing ladders, be cautious as there might be enemies lurking around. Swing across ropes accurately to get to different areas. Keep an eye out for the cats that will try to stop you. If you encounter a trap, try to avoid it or find a way to disarm it. The key is to move methodically and not rush. Check every corner and nook of the level to ensure you don't miss any burglars. Once you've captured all of them, you can progress to the next stage.
