Thank you for the feedback, we realized after we submitted it that maybe we should have put more hints in the game on how to use the objects! I think if we move forward with this game that will be something we add,
[Game Hint] Many of the things you have to combine to make the keys, and you need to combine two keys to enter the final door. Also for the clock maybe try looking under it, there is something missing from the clock that can be found there~
