You almost have it figured out, there is ONLY One puzzle left! The last thing you need is to find a way to get the necklace from the bust to use on the Room with the horse!
I do agree the game needs some Direction after you escape from the bathroom, we were gonna put some dialogue with that but with the time running out and all the other puzzles we had to implement we sorta forgot XD
The noise from below was from the Strange man's Room, to tell the player the laundry chute was now Open to go to the basement. There is a text near the laundry chute in that room to explain what puzzle makes it Open, but i think you might have missed it, but were still able to solve the puzzle, which also makes the letter disappear so you never see the letter at all, that might need a rework...
I really like how out characters portraits turned out, in the future maybe we'll some more expressions to the characters, She did felt the more stiff out of the bunch.
It makes me happy that some of the deaths gave you a bit of a scary, was worried we would have missed completely in that department.
I'm glad you spared some time to try out our game and that you still enjoyed it despite of its flaws!

SPOILER(In case you still wanna see the ending but dont wanna think more about the puzzles)
To get the necklace from the bust, first take the necklace, then after the necklace is on your inventory use the rope on the bust(the clue is the text near the bust).
ALSO there is a wall in the greenroom that you can cut to get a Key to the puppet masters Office, there is some more lore on there!
