I am simply stuck and I don't really feel that sense of progression I was hoping for (sort of like a detective game where you pick up clues that help you). It felt as if I was blindly guessing as the straws of clues I was attempting to grasp at had nothing to do with the puzzle at all (such as the instagram feed). I had a hard time trying to decipher Tom's mental state and discover what his associationn towards things was due to a lack of context built into the environments. I would have loved to continue further however, I was extremely confused with nothing to truly work with other than the hint cube. Perhaps give Tom some dialogue or have some sort of interactive pieces to clue the player into Tom's mind.
Overall, I feel hopeful for this project and only wish for the best.
Here is some footage of me trying your game so that I can give a better feeling of how I interacted with Unwording:
