In Dungeon Janitor, you play as a Janitor who has to clean up the mess left by a
Hero. However, a new Hero is coming to the dungeon, so you have to clean quickly,
because the Hero is going to make a mess when they start fighting the Dungeon's Boss.
Keep the dungeon clean enough while the Hero and Boss fight, and you'll win! Chase
your high score, and don't let the Dungeon get too dirty!
To move, use the arrow keys, and to clean press the space bar.
