I kind of feel it's a bit easy to do a travel time story again after Flow... If it ends up with the same crappy "treasure your own present and don't influence on anything in the past because then everything goes wrong" it doesn't have much meaning because you already know how it goes and what characters shouldn't do... Sorry I'm salty about all those time travel stories that expect people to live exactly the same even through they are not the same people. Let's see crappy situations and please do not try to improve because that's how things should stay.
