[Solved] Looking for short film about a girl who plays with her puppet in a cave

[Yurko]

I think I've seen this short controversial film mentioned before somewhere on this forum, but I can't find the name of the film anymore.

My memory is very rusty, I have seen it many years ago, but here is the story as I remember it:
- A girl has an alcoholic mother (and/or father?) who is (violently?) abusing her at home, and she decides to run away
- She runs to a cave (in a jungle?) where she reenacts the abuse she experienced at home with her puppet
- The ending is a bit ambiguous, but it is hinted that she commits suicide (by jumping off a cliff? Or in front of a train? I don't remember)

I think it was an Eastern European (Yugoslavian?) movie, but there are no jungles in Eastern Europe... perhaps it was from South America?

Any hints would be very much appreciated.

Do you happen to remember the year that short film was screened?

I finally found it, it is called Lyuba or Люба, and is from 1990, Russia:
