Hmm, not too shabby of a detective game! Feels like it's doing a decent job recreating that 'ace attorney' visual novel style, and its got some fancy and appealing presentation to it: pretty promising stuff!
In terms of feedback:
I know it's a demo so it's still under development, but the game was pretty rough in some aspects, especially the audio department which had tons of overused sound effects (like the droplet sound) and the music cutting in and out haphazardly. It looks pretty good in most respects, though, so I'm hoping it all gets polished in future!
It can get a bit overly verbose at times. I don't know why, for example, the chief was giving me this whole history lesson and opinion piece on the victim's backstory: not only is it too much front-loaded exposition, it feels like that should be stuff I should be picking up during the case if it is relevant, while the chief, as the hard-ass he is, should just be giving me the bare minimum starting details and let me hit the street pronto!
Maybe it's just me, but I found the rhythm of the character emotes to be a bit strange? The way they emote was just a bit awkward at times, like maybe they return to neutral too quickly instead of staying with their pose, or the explosive effects are a bit too fast and confusing, or how some side characters are frozen and lacking any sort of unique poses compared to main characters, etc.
Nothing major, but there were a few typos and grammar mistakes here and there: nothing enough to hurt comprehension so it's ok, but definitively give it a once-over when you have some time.
I do also wish that there was some more quality-of-life designs, like an easy way to fast-forward text on replays: right now, it always forces you to wait for each line to load and for the characters to do their emotes, and it's a bit awkward to have to hit the arrow on the right instead of just being able to click the text box, or the whole screen, as other visual novels typically do. I also don't know why you made it that interactables like the body in the apartment don't react on mouse-over: I feel like they should act just like the other buttons do where they get highlighted.
