This was an interesting puzzle game because I haven’t seen matryoshka dolls being used like this. :o
The puzzles were ok and relaxing, I had a good time while playing, maybe the puzzles were short but it’s nice to see this game be done in this short time!
I didn’t encounter an error or bug while playing. If this game will be expanded, I would like to rotate the camera. It wasn’t needed here but would give more opportunities to more puzzles and see more clear the map. And maybe the color changes a little bit with each different level, to give levels a bit of uniqueness. :)
Oh, and I liked the visuals and how the theme was implemented.
