I played your excellent game a few days ago and suffice it to say that it is my favourite visual novel now and I will be eagerly awaiting your next work!
I have just one question (and I think I have read most of the discussions online): Am I correct in thinking that the prologue written from Diniz's perspective and took place right before the library accident?
P.S. Really loved the ending! Luce was my favourite character in the game, so I'm really glad about the fourth requirement. Don't listen to the people who insist on Ziva or Claire being the waifu >.<
