Originally, in the game, after fighting someone in the cafeteria, you would get a fire extinguisher. Why would you need this? Well, the rest of the upstairs hallway will be blocked by fire! And because the school design is terrible, the fire will not be put out by the sprinklers. After using the fire extinguisher, it would be possible to access the rest of the school. However, I realized that there was going to be an achievement that was going require an item you didn't need to complete the game. I realized that I would basically just be wasting items, because if someone took the item, and didn't use it, they'd probably be confused. I then decided to make a puzzle where after extinguishing the fire, you'd need to clean it with the item, which is: napkins! I hope this makes the game a bit more better. Thx.
