Awesome entry! Loved the art and sound. Voice acting was really good as well. Got stuck on the 2nd puzzle as well tho. Might come back to it with a fresh mind.
Found 2 bugs that you might want to know about. 1 is just silly but not game breaking. If you are inspecting an item like a book and you press Tab to view your inventory, exiting the inventory allows you to walk around. However the inspected item is still floating out as if being inspected. You even maintain control of it so you can use the scroll wheel to scale it in the room haha.
2nd bug can break the puzzles possibly. I was able to pickup the item in the book shelf. I won't say more so others don't break it but seems to be that the raycast could be clipping through?
