Not sure what you mean? You need to go to the water dispenser, press "E" to interact and use your mouse or arrow keys to select "YES", then a cup will appear to fill and you will automatically collect - then go to the door and you will be able to leave

I tried that and no prompt opened up. The prompt opened up for the door for yes or no for some reason and I clicked yes but it did nothing and the prompt stayed stuck on the screen for a while. But it never appeared for the water dispenser. It seems like a great game and I love the vhs style, I just wish I was able to play it 😢 I'll try again soon. Thanks for responding!
