This is lovely. I am kind of a sap so take this as you may, but the intro brought tears to my eyes. I love non horror sci-fi and this really did that well. It is gently written but also very matter of factly that life does in fact come to an end and this is these characters' time.
I appreciate the solo option and that it can be played without a GM with two people, but that it also is encouraged to play with a group. It’s nicely versatile and I think would be enjoyable at any player count.
I saw on your itch page that this is the first TTRPG you’ve written and completed and I just wanted to note that I hope it’s the first of many. Beth and I are so happy to be a part of motivating you to give it a shot!
