Nice premise. Slightly obscure mechanics (in particular the "distraction" variable) but this is somewhat mitigated by the brevity. Otherwise, it's a neat package that speaks of an experience common to many of us.
In fact, it resonates to the point I might share this with my colleagues via Facebook, lol. Seeing as for many of us, we're constantly procrastinating from sitting our next set of exams even while working full time. Mine are only 110 days away, so what the heck am I doing here, sigh.
