This game has such an amazing visual style! You did a really good job of making the important objects distinct and recognizable so the player wouldn't get confused and pass them up. I also really like the sort of operating system window thing you had going on with the dialogue boxes. It was a really cool and interesting way to do it, and it was very intuitive.
Your transitions were also so nice looking! I loved those!
I did get a little confused a few times when walking into the areas. It seems like theres only one spawn point for the player so sometimes I walked in from one side of a room and when I appeared in the level it looked like I had just come from the opposite side, so I ended up walking back to where I started. Small nitpick, though, since I got it figured out after a moment.
Really cool mystery game!
