Very high praise there, especially since you've played The Return of the Obra Dinner and the Ace Attorney series!
I'm really glad you enjoyed it, it seems like this game may have been made for you!
The issue of simply seeing the evidence I do agree with, the main reason for that system is time. If it wasn't obvious that you had enough evidence, then the accused option showing up could seem arbitrary. If I had the accused button for everyone always active, then it would mean you'd have to be able to submit any evidence to anyone, which I didn't have time to implement.
I am glad you enjoyed it though!
