Pit Pot: The Magical Castle

The princess has been kidnapped and held captive inside the castle, and your
job is to navigate each room by collecting all the goodies, and killing
monsters using the hammer that a witch gave you. Once you have done that, you
must get through one of the open doorways. To navigate the room, you can walk
either on the gray tiles, or the yellow ones that surround them. Monsters also
can walk on these gray tiles, but you can make them fall down if you smash a
tile that they’re on. The monsters will regenerate in the room after five
seconds.

Be careful of dragons that will throw fireballs at you. If you get hit by a
dragon, its fireball, or one of the monsters, you will lose a life. You can
collect keys that will open locked doorways, so that you can exit through
them. Some power-ups can also be collected. Collecting hearts, for example,
will freeze all monsters on screen for a limited amount of time, giving you
the opportunity of killing them.
