I really liked the story, and the way you write, I loved the concept of Phil living once again his forgotten memories, and, though I have my critique, it was a really pleasant experience and I much liked it. What I didn't like that much may be just really a preference of mine, but it is towards the ending, I found it a bit too self explanatory.
[Spoiler ahead]
I really loved finding out about Phil being the secret lover of Catherine, and that Jack dying was a mere doll, but I loved finding out about those things, when it was clearly stated in the ending it made me lose a bit of that amusement — it doesn't make the book bad or anything, the entire piece was too good to be ruined by such detail, but idk, what amuses me in books is to read them and feel like I've understood them, through getting immersed into the story, so when the story is very exposing about itself, idk, just feels like a summary of itself within itself, if that makes any sense.
[Spoiler is over]
Nonetheless, you write very well and I look forward to reading more of your work! I don't demand you to change your style based on my preferences (no one can even ask such thing, it's your work and it should be about you and your likes, not mine or someone else's), but just wanted to let you know. Hope you saw this as something positive, because the experience really was for me, have a nice time, a keep up with your work, it's great!
