Very fun! I liked the background effect in the first part, though I wish that trippy effect carried through elsewhere. I enjoyed poking around all the different rooms and seeing how they changed, and the safe puzzle was a nice touch. My specific choices didn't seem to influence the middle of the story so much as they decided which ending I got. This works alright, though I wonder if there could be any way to influence my environment before the end?
The red room was hard to look at, though, and while I understand that to be the intention, it could probably be desaturated just a little bit. Otherwise, a solid, very funny experience.
