Nice little project! Good job! Solo project?
A few comments
- It's very easy and intuitive to get into. Well done!
- Having a knife that you can't pick up in a horror themed game is such a bad tease.

- Haven't spend ages on it. But was kind of stuck when I got to the white walled lower level basement.
- Intuitively I dragged the objects from the inventory onto doors etc. You should make it possible or inform the player it is not possible when he does so. The cogwheel icon broadly indicates 'settings'. Perhaps a hand icon would be more relevant?
- Missing some sort of twist to the puzzle formula. That makes your game special.
- Missing better writing and world building. Obviously there is content I did not experience. But something that pulls you more in to the lore of the world. Not tons of lines. But small effective lines could be used when observing objects in the world. Or journal entries describing event in the world a bit more detailed.
There seems to be no story hints to the ghost girl walking by. Is she a centerpiece of the story?
- A bit more.. but not overdoing it.. interesting ghostly events would be welcome. Perhaps the player briefly sees something strange when looking out of a window.
- Obviously saving game progression.
- Needless to say. You box coat could use a makeover.
cheers!
