I felt really bad when I had to kill Nathan :(
Anyways, the idea of count down as a time in life with the memories is REALLY good
The mechanics is simple and also complements the narrative very well, without drawing all the attention
The character development is great, even with limited screen time, we get to know them well
In the ending, I got a feeling of: “Well, it’s really over” and these feelings hit me so hard LOL
Well done!
