really enjoyed the game
I didn't get whether the rat is a metaphor for the child (which either implies that you play both the driver and the parent of the kid, or that it's just a way the driver is imagining/dreaming how the parents must have felt) or the rat was real and the situation is just so similar that it brought memories of the incident back to the character. maybe the developers wanted to leave that question open to interpretation, but most likely I am just stupid and didn't understand it.
really cool idea, I recommend it
