The pixel art looks very nice and detailed.
As mentioned, it ends at "Why can't I play toy from k?". It seems that there are some missing contents afterwards.
As for the story, I think it is interesting combining the unboxing-style game play and a sad story. It would be better to mention more about "k" and "I" too.
Or maybe go more stereotype approach to separate toys for boy and girl to better construct the story.
