Great renders, interesting premise, beauties, but some of the characterizations are just way off.
The MC supposedly lost all his memories, and in that case, even with your family, you'll act neutral, yet the guy is this goody-doody two shoes who's instantly is on the paragon route. In some situations, the lack of reply choices were annoying, or how we can progress, like the Eva scene. The little sister is another miss, with being over the top as the "bad girl in the family" cliché. All those "WORMS" and shit within one convo won't come off as antagonistic, but annoying, in a way that you just want to click over the dialogues rather being angry with her for how she's acting. Another thing is the whole secrecy around the accident from the family members, usually when a coma patient wakes up with an amnesia, the first question they ask is if they remember what happened, and if not they tell them, to try trigger some effect that could help to recover the memory, rather than keeping silent about it, I get the suspense effect for the story, but in this case it doesn't work, unlike with a story where the main character have to piece all the puzzles together by themselves because they have no one else to depend on.
Other than this, it was a good start, and has great potential, we'll see what it becomes.
