I downloaded it because I fell in love with the cover illustration!
It was a very fresh and interesting experience to experience the events happening in the world in reverse order and then take on the final day again.
I felt that the skills I got on the first day were not that strong.
However, I felt that once you get back to that point, you can play without getting your days back even if you get hit, which I felt was kind and good for the play experience!
