First of all, congratulations for finishing the first book :D.
I just finished reading the novel (I had never read any previous version before) and I loved it, the drawing, the music, the story, the expressions, I really liked everything.
I'm looking forward to Dryz <3
The only thing I would have liked is that in the first chapter the relationship between Lyall and Richter would have been extended a little bit more (for example in the first dinner they had, I would have liked to see what they talked about, or the days they skipped, take advantage of one or the other to show how the connection between the two of them existed or grew.
I think those simple/everyday moments are the ones that make you get attached to the characters and feel related/friended/acquainted with them).
And a little detail that I saw in the pc version, the normal thing is that when a character talks his silhouette appears in the textbox, sometimes the Richter appeared for a moment even if he wasn't talking and wasn't in that conversation and then he disappeared and the correct character appeared.
And in the mobile version, in the gallery, I think there is only one button to forward the images, so I had to flip through all the images to go back to see another one.
(I don't know if this only happened to me because of some installation/unzipping/downloading error).
