No idea if the dev reads these forums, but in case they do:
I really like this game, it's a little bit unpolished but it has a ton of potential and is already really enjoyable in its own right, this just means it could go even further if this keeps up!
The only real issue I see for now is that there seems to be an almost bigger focus on flashbacks than events happening in the current timeline. I get why, because of how the story is set up, but there's still a lot of leeway and I think there are risks with doing too many flashbacks. The problem with flashbacks is they will never feel as rewarding as something going on in the main timeline. It's even more of an issue here because the game has introduced or hinted as so many different characters so it will feel extra unrewarding being stuck in the past doing stuff that is essentially "old news" when we could be meeting all these new interesting characters and develop our relationships with them in a timeline where it feels much more rewarding.
That being said, I'm not saying stop doing flashbacks altogether, I think with how the story is set up they become pretty necessary. But there should be a lot of careful thought put into how much development time and "screen time" is put into the flashbacks, these scenes should probably be as short as they can be while still holding the same information and only happen when very, very necessary. Most of the time from the players view should be spent in the "real" timeline.
