Very nice game. I like it :) Make me think of Myst :P
But I still dont have any clue of the meaning of the paper that have this message "When i asked him for explanation, he drew me this:" and some kind of grind with 8 dots.
You removed the right-click and "Play" ability, preventing cheats.
I am very happy to give a 5 because this game is great. Yeah, it could have done with more plot though, or if the plot made more sense.
