You effectively used a few simple yet well executed ideas and mechanics to make a tense experience. It was fun to struggle with influencing the dice. Maybe there could have been more to it than simply landing on 2, though the time limit prevents this from getting too repetitive. And I think the repetition played into the themes of the story well--it seemed futile and desperate to keep trying to land on 2. It might be interesting if other faces could have different effects that you must try to avoid, which would make each roll a bit more varied.
I was actually a little afraid by the end! Good job!
