Hahahaha, thank you for your long, very generous, and excited commentary! It is good to know the humor is appreciated and this is the kind of stuff that makes making these hacks worthwhile. Yes, depending on the song LG will respond to different people differently, commenting based on the song that she is listening to. I think the Aimolette pizza call and maybe Claire's call depend on this, as also does the shower scene. I am so glad someone committed to eating the sugar jar 100 times. I was hoping one person would try that, haha.
And yes, you can actually get the pizza at the end! What you have to do is on the last day, in the kitchen make sure you talk to the doll but leave it there. Turn the radio back on, it won't come on immediately, but you will get a weird noise and the girl will say it's heating up. When you go back into the main hall, you should hear a doorbell. You can answer the door or run into the kitchen and living room and bathroom and the dialogue will change a bit. Whatever the case, you can now open the door (which will change whether or not you got locked IN the house via visiting the void too much) and get the pizzas. Once the pizzas are in the house, you can then go up and talk to Zera. You should then be able to get the true ending.
Once again, thanks for your commentary! I sincerely enjoyed it!
