Sweep!

It's hard to say where you actually are, but your objective is clear: clean all chimneys. You can carry one item at a time. Default is a stone to throw at enemies like rats and ghosts. Once thrown, a new stone will appear in your hand. On the map you can find buckets of water and brushes. Pick up a bucket and run into a fire. It will remove the fire obstacle from the map. Pick up a brush and run into a chimney. It will remove the chimney from the map and you have one less to clean. When walking left and right, you can spot enemies quite early. But walking up and down lets you walk into enemies more often than you like, because the screen size is limited by a large status panel on the bottom of the screen. The panel shows the "temperature", which acts like a level timer.
