Very good game! Fun, interesting and entertaining dialogue. Found 2 big flaws tho.
1.
While doing the rib-music-puzzle the sound started messing up. It sounded like it was duplicating every few seconds and it made the game lag like hell. I had to restart the game after 3-4 minutes trying to get the puzzle right because it was lagging so bad and the sounds sounded like demonic chants.

When going to the river, there is a way to completely crash the game. When you put your curser slightly above the "River" door, it'll show the curser as the arrow pointing down like the normal door ones but it will say "Stone Man". When you choose to interact nothing major will happen and Doris will just go down to the River. But if you're close enough to the Stone Man and choose to interact, the dialogue will pop up AND Doris will go down to the River. You won't be able to move or do anything when you're down at the river and Doris will have her dialogue above her head. Now you can get out of this if you click on the text of dialogue until the dialogue is over. The second "version" of this is when you do the same as above but before the screen changes to the River, you skip the first line of the dialogue, which is Doris'. Just before you're down at the river you'll see the Stone Woman's dialogue above her head. When that happens, the game is completely broken and nothing works. You can't interact with anything, Doris is skipping everywhere and the game just seems "dead". The only way to get out of this is to refresh the game.
Hope this helps
