[CONTAIN SPOILERS]
Exceptional. The whole experience of playing this game was very smooth and cleverly interactive in a way that locks you in in a very good way and not the 'insanely hard to the point it makes you want to give up the game' kind of way.
The storyline and plot was also really captivating. There's a few things that still remained unexplained, and I'm still hoping that we could see more things from Victor's point of view. (I'm shameless with the fact that I think I favor Victor a little bit more, hence why I want to see more of him and get to know him better, probably due to my personality leaning more towards Vincent and I think every Vincent needs their own Victor.) I believe the key element to making your game timeless is to keep your players curious about the characters in the game, and you nailed this right where it hits good. The way you write the relationships between each characters and how they relate to each other are really... all I can say is you're a writer who cares about all your characters equally and it showed in the game. I'm just at loss of words, especially at how you unfold Victor and Vincent's relationship and just how dependent they actually are to each other. Chapter 4 ending was sort of unexpected, but I do understand why it ended up they way it did.
As for the background music, they are all fitting for every situation and scene in the game. I'm a really meticulous person when it comes to this aspect, and it's one of the aspect that most games overlooked because it seemed unimportant enough compared to other striking aspects like visual and storyline. But seeing how each scene in this game are accompanied by music and sounds that truly fit the vibe, I can easily tell that you really took your time in choosing each of them carefully.
If I were you, I would be really proud to be the creator of Vincent: The Secret of Myers. Will definitely come back to this once new chapters are out and ready. Thank you very much for creating this amazing masterpiece and please, do keep up the good job.
Much love,
June.
