This was really great - can't believe you've had so few rating so far. There are a lot of people missing out on this excellent escape room game. It had a lot of similar elements to the game we made, but yours is a lot higher poly. I thought graphically it was very beautiful. I loved the surrealist element of having a portal in the cupboard and food in the bathroom too. Very inventive.
The puzzles were also well crafted - I particularly liked the one that made use of the radio. Very clever!
One suggestion that would have improved the experience is making the object interaction a little less precise. Weirdly I found that I couldn't pick some keys up or open some draws if I was too close to them. I kept having to move myself back bit by bit before I was at the correct distance.
There was also a small bug in the bedroom where, if you moved close to the wall with the drawer, you could actually phase through it.
Great work overall though! Extra points for doing a proper Mac build :)
