Interesting game, I enjoyed the time mechanic and how it physically moved faster while playing the game and slowed while studying. It is a simple idea that is well executed. It plays into the theme very nicely as well.
If you wanted to improve, I suggest making the game a lot shorter, maybe 1 day instead of 7. That would allow you to still get the same point across without forcing the play to give a huge time investment.
Overall, cool game!
