I wonder if it would be a good idea to give the mc a voice in critical situations only or where we really need to see what he has to say, like the letter Noah leaves behind in the true ending.
One things that annoys me with speech bubbles is that the same speech bubble is used for "ah, I stepped in a puddle" and for "You betrayed me!". I know its stupid, but sometimes I wish the speech bubble appear several times, maybe even interrupting the other characters, sort of like "enough bullshit", in times of revealing the enemy's plan. And then we get what the mc said by the other's responses, like normal. Even if he doesnt have a voice for us to see, I want the other characters to treat him like he has one when he's obviously pissed or really has somthing to say.
I would clap in my room if the mc suddenly went "SHUT THE FUCK UP!" when the heroines be yapping excuses, and then go back to speech bubbles lol.
I dunno, all these games have fantastic story and conflict, towards the end I actually enjoy them as great drama literature or stories, but the conflicts peaks between mc and heroines, the "how could you?" moments, the confrontation moments with them always feel so unsatisfying. One times I really liked how this was done is with Celis in true ending. You dont trust her again and she works to earn your trust back.
