Very creative/cool mechanic to have the character interpretation as a puzzle, and I can't wait to see how the game changes as Tom's life goes on.
Although, in puzzles, it would help if the turning of the blocks wouldn't be so slow, as it feels irritating more than atmospheric to have turning the block take so much time. Also, sometimes when i had solved a puzzle I had to go to the menu and back for the game to register it (although I first thought it was a clever effect, when it appeared in the "give up" puzzle :D)
All in all the idea is very cool for narrative game and I see a lot of potential!
