I'm sorry, could you explain to me the elevator pause and the watermelon glitch in more detail please? Like where exactly do you need to place the melon slice near the elevator, do you need to put it right outside the elevator, or leave a trail, or be standing directly on top of the watermelon? Is that just a theory or has that actually worked for you? And how do you do the elevator interaction pause, do I just pause on the elevator screen while pressing and holding LMB on the slider scroll, then hover the cursor over the approximate slider distance and unpause with finger with touchscreen laptop, then quickly release LMB hoping to have the correct number, then repeat with other sliders?
Elevator pause: All you have to do is hit the pause button and the interact button at the same time, in my case. I press "Q" and "E" while looking at the monitor. You should be able to input all 10 numbers at once, click check, and then tap return to get out of pause screen.
Watermelon glitch: Tested it, place watermelon piece out of Marzia's pathway and be within range of that piece. Marzia will run up to you and just stand there, if done successfully.
Screenshot: Marzia standing next to me inside the elevator.
Also, biggest tip. Marzia can't open doors at all before the final chase in current version! Lure her into one of the 6 beginning classrooms, and pray she doesn't get released by Headteacher. Makes beginning part easier.
(Let me know how it works out.)
