I played and finished teh game yesterday night. I had no further problems with all the other puzzles althouh I was a bit confused about the chemicals. I really really liked it, I was on edge teh whole time expecting a monster to chase me. The scene in the lounge room was pretty cool. I was a bit confused by the "stay" ending though, it's a bit of a cliffhanger. There's clearly a lot of work put into this and I love the care put in the details and the environments.
