Very cute characters! Loved dialogues between them. The style is nice, the music is relaxing and fits the game well, and I like the story a lot. I like how it looks a bit like fairy tale (or a fun quest for children), but with serious mood, cause their mom is missing and her letters sound pretty serious.
That's cool that we can interact with the world, I love your attention to details. I enjoyed clicking on everything and reading girls' comments ^^
I especially liked the moment in the museum where we can help two lonely NPCs by suggesting spending time together. And the main plot is intriguing and interesting (though I got stuck after visiting the museum. I guess there's just some bug which doesn't let to use the bus station. Tried to download fixed version cause wanted to see how the story ends, but parent.exe file fails to extract its content properly. It just freezes in the process, hmmm)
Overall, that's an adorable and cool project, enjoyed playing it. Nice work!
