I love the concept of having to align these two values as they count down and I think you pulled it off quite well. The graphics look nice and everything feels very polished. I also really like the philosophical aspect of life/choices being more complex as the individuals accrue years/regrets, because life do be like that.
My constructive feedback would be that there isn't enough time to read the descriptions at each of the life events and/or the descriptions are too long. I feel like in a game about exploring morality the context/justification of those choices are important. I also felt that it became a bit too easy once the years and regrets became very high, it was basically "choose whatever will decrease by the most". Though I can see why you went that route because otherwise it would essentially require actually doing math haha. From that perspective I think you made the right choice.
