The Grave of Thorns

NOTE: The previous version was incomplete, and a new version has been uploaded. Enjoy solving the puzzles. The manual is REQUIRED to solve the riddles of this game. Be sure to download it and ideally print it off to have it at your side while you play it.

Arriving at the Sacred Burial Grounds, it is your job to bring peace to the restless soul located there by performing a funerary ritual. However, it won't be easy: the valuable treasures necessary for this are enclosed in chests across the island, which can only be opened by deciphering the cryptic clues given to you.

With patience, the mysteries will unravel, and the puzzle will be solved.

Stuck? Feel free to discuss puzzles below in the comments with other players but be warned: spoilers will likely reduce the enjoyment of the game.

Controls (for reference):

• WASD: Move Around
  
• E: Open Inventory / Select and Equip Held Item with LMB
  • Also focuses the cursor, so if your browser doesn't focus immediately, open and close your inventory.
• Escape: Open Settings Menu
  • You may save your game via "Save and Quit", but only items are carried over between saves and it is not well-tested. I do not take any responsibility for incompletable game saves, and highly suggest you attempt to complete the game in one go.

• Mouse: Look Around
  
• LMB: Select Item (in menu)
• RMB: Use Held Item (only works with some items)
• Mouse Wheel / Up and Down Arrows: Change Tuner Frequency (only works with a specific item)

-CW: References to self-harm and suicide, contains flashing lights and shocking imagery-

I highly recommend you play on the Windows build. The HTML5 build has severe audio buffering issues, and it is far from the best way to play the game.
