You did a good job making your characters feel like real people. Even though I was only seeing a small snippet of their life, they felt like there was more to them. It helped me feel engaged in the story and had me wanting more when it was done.
I liked how when I finished the prologue, there was a score card letting me know how I did. It encouraged me to go back and play through it again to try to find what I had missed. The next part was also called prologue, instead of Chapter 1. I only acknowledged that it probably should have said Chapter 1 because of reading your devlogs, as that part still felt like it could be part of the prologue.
I was also grateful for the content warning at the beginning of the game. It let me mentally prepare myself and make sure I was in the right headspace before beginning. You may want to include a comment about child abuse in it. I know for some people that is a bigger trigger for them, so a little advanced warning might be a good idea.
I noticed a couple of issues. The next morning, some of the text for places like the bathroom and the puzzle on the table were the same as they were after you checked on mom and before returning to your room overnight.
The other one was after I completed the game and tried start a new one. It skipped the opening part, going straight to mom calling Sara down for dinner. It continued to the turning off the TV scene, where I could still see the New and Load options on screen. When I tried to turn the TV off, I got the following error message: “Video con ID 02 non trovato”. I had to close the game completely in order to restart from the beginning.
I can’t really say that I had fun playing the game, but I do think it is a good game and worth playing. So far you are handling a rough subject matter well and with care.
