- First of all, what stands out the most to me, is the font. Since Ace Attorney has a pretty familiar and well known one, it just seems off when it's a different one, especially if it's not even a bit similar. Same goes for the textboxes and the thingy for the names. I think it would be possible to download the font somewhere, so it shouldn't be a very big problem to solve but one with a very big impact on the overal feel of the game. Also, like someone on youtube already noted, the text should come into focus from left to right (preferably lettter by letter, like in the games itself, but that would be hard I guess) instead of coming into focus from the middle. Because you can't begin reading before the start of the sentence is there, you have to wait till everything's there, which is kind of annoying.
- Next, you should really start making some sort of script. Without a story, you can make as many amazing game-mechanics as you like, but there won't be a real game. It's really, really, REALLY important.
- Everything that comes next, is part of the scriptwriting, so I can't really say anything more right now. Things like characters, the way they talk, whether you want a lot of cameo's or not, places where the story will take place, reasons for murder/theft/whatever crime occured, etc. I can't give feedback without something to go from.
- Oh, talking about locations, do you want to add some investigations sequences? Do you plan to make them interactive too, or do you want some sort of movie, or will everything be courtroom only like the starting cases and case 4 from trials and tribulations? For any of these options, how do you plan to do it?

If you need help/ideas with any of these, please let me know. I would be very happy to help!

Just downloaded the font and I'm ready to change!
The first two videos do that, but I quickly found a way to change that because even I was getting annoyed with that. xD
A script is what was next. Truuuuuust me, when I say this thing is for testing mechanics, that's precisely what I mean. The true project underneath it (the one I was trying to do before I even thought of making it interactive) is far from development. So speaking about the plot now would probably turn this into a pipe dream, so I'd rather keep building step by step until I'm ready. Though of course, a script should be in the making now, if not the near future.
The investigating part is where I was going to try and take the testing phase next. I don't really have many ideas as far as how I could do that, but ultimately I think I'll end up recreating something from case 2 in the first game just so I can test if youtube could handle that.
As far as standing in front of people and talking to them (asking the specific questions), I can't really do that. Asking questions would make waaaayyy too many video variations, so I'll have them say all they need to say in the beginning, and you can present whatever evidence you need to talk to them about when the talk sequence is done.
Thanks very much for your support, I will say I will need help with pretty much everything you've talked about except for the font and talking part, because there's quite a bit I have to do before I can get to that point, even.

But it's a great honor to have your support and help. I greatly greatly appreciate it.
