I completed the first 2 difficulties and honestly I really liked the camera work. One thing I would fix is that when there are more than 2 doors and you step back from a door you cant see the doors on other corner and you have to click doors one by one to get to the remaining doors.
The clues are good but a few times I had similar clues and got them wrong and didn't really understand why.
Overall the game is well made. Good job!
