The game is alright but I don't quite understand the keys.
first playthrough i was missing 4 keys then completed it, 2nd i couldn't find the last one and then third I just ran to the end to see if I needed any keys... and you don't. I also didn't figure out how the colour of the keys and the colour paint on the locks match.
Did enjoy the spookiness of the whole game especially the hook room.
I seem to looking forward to more a puzzle game honestly.
