I really liked your game. Tried it several times, but only could save two of them. The art was nice (liked the colour palette), and the music and gamefeel were also pretty good! It fit the theme very well, too.
Only thing that I would recommend is let the children follow the mother. I wasn't able to explore the world at all - I saw some coins at the right on top of a cliff, but it wasn't possible to go there because the enemys were already killing all my children. All in all, a great entry!
