Fascinating game! The art style is phenominal, and the music by itself really had me on edge, I was unable to beat the game, I think I was missing one item from the ritual maybe?
In any case, I did come across a few interesting bugs!
Bug number one!: In that area with the fleshy stuff and where you get the totem with the eye on it? Well to get it you move those flesh things and stuff, I noticed that you can keep resetting the puzzle after completion by making a purposeful mistake, after which you can beat the puzzle again and get another totem, infinitely.
Bug number two!: Not wholly sure how this one happened, but it was at the ritual circle where I had the bear, candle and totem placed and was unsure where to go from here, I clicked and dragged the bear across the screen and that seemed to jump me straight into a settings menu, from there when I clicked main menu, and then clicked play, I was at game start, WITH all my items in my inventory and with this peculiar encounter when I investigated the ritual circle again:

and lastly bug number three!: After collecting items from places, the E clue popup still appears where they once were, kinda misleading!
Other than that, this was an amazing and fun game, I'm definitely going to try my hand and beat it sometime!
