In this game, you call your son to apologize for not picking him up.
The reason you didn't pick him up? That's...complicated. The actual answer depends on your choices. You have a few 'main' choices and then a chance to add details.
The system is interesting, with realist options on what to do with the voicemail once you run out of time.
I played about 3 or 4 times and liked each of them. An expanded version of this would be fascinating, but a lot of the appeal here is from the wild branching, and that would quickly get out of hand.
