first of all, before starting my actual review, I definitely want to recommend anyone to play the game in a pop up, preferably in full screen for the best experience
now my review:
I really loved the game, I also played the first trader of stories game, this one was even better in my opinion than the first one
I loved the music and artwork
I also loved how you can examine so many things, and although some of them might not add too much to the story it's fun, and it some words for the story game can be found during examining, so I like how you 'learn' those words during your adventure
I can however imagine that some puzzles can be confusing if you never played anything like it before (e.g. the cloud separating mahjong puzzle), I myself had difficulty with the story game, because I thought I had all the words I could get at that moment, but it turned out I didn't, and anywhere else in the story I couldn't really find anything to progress with, though consulting the walktrough, I found that I missed a word, and by finding that word, I also found another part which I could use to progress
so perhaps you should consider giving the gamer short instructions on the puzzles, and with the story game, perhaps it'd be nice to have to possibility to see what words you're still missing, so you know it when you need to search for more words
I also really like the fact that you can import a game, so you can continue playing on another computer, or even share the code with others, to show them at what point you're stuck
the eye-tool was also a big help during some scenes when I was stuck,
definitely worth 4.5 stars, add some puzzle instructions and a help tool for the puzzles and I'd make it 5 stars
