Hello! I played your game and i here is my feedback:

I would change the game icons a little, it took me a while to realize that the skull on the right side was a settings button, put it together with the others on the title screen as text, and I would also change the exit buttons to a text written 'back' or an 'x' icon.

I would also choose a font that supports accents with ^ ~ ` ´ and so on. When I change to languages that use these writing rules the font does not show the characters, eg: eng = BOOKEY MANOR, pt = MANS O ASSUSTADORA, the "Ã" was removed.

I think you could add an extra incentive for the player to keep collecting keys, for example if you don't collect keys constantly the character will get scared and if you reach the maximum you lose, also add something more special for the residents, like you have to hide from them or close your eyes, if you see them for too long they will cause damage or kill you. This is my opinion on what could be improved in your project, because just clicking on the keys without much objective other than collecting points becomes a bit repetitive. I wish you good luck with your game!
