Well well, since the game is complete now, I just had to give it a try!
I really liked this one, I think you pulled the overall concept and idea of the jam very well! As always, you managed the life-concepts and depths of the characters (well, mostly Mina in this one! Althought Yuuta did give a few glimpses of the way he is too, clearly a workaholic lol) very well! It is quite interesting to see Mina's one-in-a-hundred-years potential be prevented to shine by life's situations. And it is also very lovely to see it shine when the time came.
I loved what you did with the UI! Specially the loading screen, I don't think I've seen many online ren'py versions that have a customized loading screen! Same with the little animations and sound effects, they gave a very dynamic touch to it!
As for the characters, as I said above, I just love both of them. It really felt like the first chapter of an anime lol
Once again, great work Marie! I really enjoyed this one and it's message of hope, and certainly feel like you could make it a series!
