Thanks for playing! I'm a bit frustrated that I didn't have the time to make lockers more viable, so that you'd still want to use them when you knew they weren't completely safe. It was definitely a feeling I wanted to convey, something along the lines of "she's playing a game with me, and she can decide to change the rules on a whim" kind of feeling.
I just did an update to fix the issue with the last cutscene, so if you're interested, please feel free to check it out! (I'm really not used to this dialog system yet, lots of kinks to work out)
