Awesome work. I played this game multiple times now. I don't have much to say about it, except it's have a really good concept, playing with age and legacy, and also relying on that.
I agree on the reamarks of @Munro. But there is something frustrating me when I was playing, that is the box physics, it makes the game really hard. I hope you remove that the box rotation and fall when on the edge.
Overall the game was enjoyable, Nice job!
