This game is a sequel to The Little Match Girl, a game that was about hopping through various fantasies to solve problems in each of them.
This game is a bit different, with a different premise (you are an assassin) and a different configuration of dreams (nested, rather than interconnected).
Like the Castle Balderstone games, this give the impression of being a grab-bag of passion projects, where some idea or thread was worked on in great detail and then the rest of a game scaffolded around it and polished till smooth.
The first few visions are pretty light and easy, just follow directions and look around. This can be fun, especially in shorter games, and the worldbuilding was nice with fun fake-outs, and there was animation and title sequences and colors, but by the end of the second one I felt like I could use a little more to dig into. The next world had more involved puzzles (with another fun fake-out), and the one after that was incredibly dense, filled with puzzles of all kind, which contrasted nicely with earlier material.
Overall:
+Polish: The game was smooth and worked well.
+Descriptiveness: The settings were very vivid, especially the second and last, and I could picture everything.
+Interactivity: Like I said above, there was a good overall balance of streamlined playthrough and puzzles.
+Emotional impact: I was entertained. At one point I took out my plans for my next game and took down some notes.
+Would I play it again? Yeah, I'll probably go through all the games in order when the others come out.
