Fun and surprisingly tricky! Artstyle is clean and appealing, song was lovely, and some of these levels took some real precision and lateral thinking to beat. I noticed that if the big mamushka grabbed both the other dolls, the one she grabbed first wouldn't be inside her, which would make sense if she grabs the medium doll first because that one could open too, but if she grabs the small doll first the small doll is just gone. A couple animation variants for each scenario would be a very appealing addition, I think. I also noticed that the smallest doll seems to be able to stand on spikes for a moment, but then if you make any move she immediately breaks. Speaking of, I love that the death animation is just a sudden breaking. This was great, good job.
