I'll be very honest here:
I decided to test this "casemaker"... The thing is, it wasn't as good as I thought it would be. I didn't meant to offend, but the thing is. The Cross-Examination part was almost good, but the Court Records screen was extremely messed up. If I were on your shoes, my first click at an evidence would result in telling the information of the evidence itself, and then the second click would result in Objection. You see the connection here? Attorney Games must have informations on the evidences, nontheless it's pointless. Rating for Cross-Examination: 3.00/5.00
The second part was, eh. You only included the "Examine" part. Attorney Games mostly have "Move", "Talk". "Present" is somewhat optional, but "Move" and "Talk" are not. Plus, the background was an AAI Background, I thought more of an AA Background, tbh. Not forcing you or anything, but it just looks way simple. Rating for Investigation: 3.00/5.00
Just to let you know, Powerpoint has a tendency to move to the next slide anytime a player wants to, so there's an unbelievably highest chance possible for the players to "Cheat". I don't know if there's anyway to solve this, tho.
Total Rating: 6.00 / 10.00
To be honest, I'd give you a 6.00 out of 10.00, but seeing how this is your first attempt, I'll give you 0.50 more.
