Aaaa, love the character interactions! and the story plot idea too! Or... what is the words... I mean, the cases? the events? I guess it's just fun figuring out who is what and involved in what events in what kind of way... And to think that the story is just unfolding in one setting!
Sure, there are still things that could be improved; like for example, there are still some dialogues shown with inappropriate character name, and I notice one instance where the sprite is taken out late from the screen. I imagine if there had been more time and hands on deck, the GUI could use some customization, and the script could use help from an editor or co-writer to smooth out the english. Who knows, even more details to the story elements (like the names of people and instances involved at the outskirt of the story).
But anyway--for a game made solo in a month and half, you did a good job! uwu)b
