I don't even know what to say. I downloaded this game because I thought it was going to be short, fun and a bit whacky and sure enough it turned out to be hillarious. But also heartbreaking, warm, relatable and absolutely lovely.
First of all: Jazz is the best. Hands down. Best protagonist I've ever witnessed in such a game. She has so much personality and I think I might have found some of my new favorite swear words, ooopsie-freaking-macy-daisy. I love her. And her backstory broke my heart. I honestly cried during my first playthrough on Carol's route. Especially the scene where Jin is comforting her made me bawl my eyes out.
I also really loved Laby and his crying. Actually all of the family interactions were great, I could really feel the love between all of the families, Noct's and Carol's. It's amazing how well you captured family dynamics. The characters in general felt so fleshed out and each of them was interesting in their own way. I find myself wondering how their lives go on after the story and that is an amazing feat for a storyteller. I read every single bonus story and I'm usually not one for extra stuff.
The last thing that really got me was the representation of mental health problems. Oh my gosh, you did it really well. It was an integral part of the story while not having the whole focus just on how bad it is to have either depression or anxiety. Carol might have been a bit over the top with his furious blushing, but then again that is his character and I love him, but Noct's depression was just so spot on, I'm honestly impressed.
So overall I simply have to say good job. On one hand you made me cry very hard, on the other I never laughed out loud while playing a visual novel before and I have played my fair share. I really like your humour and story telling. So keep it up! I'm excited to see what you are up to next.
(Also if you behind the screen read this whole text now, this is a definite recommendation to play this game, if you haven't figured that out yourself by now!)
