Here I will explain a few things before you get confused with the gameplay

1. You can only hold your breath while inside the locker.

2. To avoid Lisa when you are in the office, just keep your mouse over her. even if you are inside the locker.

3. Wait for the hallway animation to finish so that Lisa leaves definitively.

4. In one of the three death minigames, there's a secret.

If you find any bugs, let me know so I can fix them.

Now enjoy the game :)
