This is a good looking VN and the time loop thing is interesting, although its a bit confusing. In my play session, since I left the VN on for a bit and went to do something else and came back and it had gotten to the time out ending, then playing it again it skipped to some loop part, so like I missed the whole time stone thing.
so suggestions:
a) have a reset button somewhere? so can start over from scratch. Or some option somehow
b) would be nice if you show some sort of way of showing the paths taken.
