Great game! Loved the mood, art and the difficulty of the puzzles. As others have said, the puzzles are quite challenging and I think a hint system/puzzle guide text file would have been useful for the duration of the jam.
I managed to open the door and would like to know if I got the logic behind the number code right:
SPOILER!!!
Is the solution based on the color sequence in the picture beside the clock, Blue, Red, Green, Yellow?
Blue - Time on the blue clock
Red - Number of red objects? Meaning the red carpets (I'm most unsure about this)
Green - Number of green shelves
Yellow - Number of objects on the shelf with the yellow object
If this is correct, then I felt that the note beside the blue clock was a huge misdirection because it made me believe that the solution would be the time on all of the clocks, but there was only 2.
