With that being said, in 45 minutes they've done a pretty good job telling a story. If they got like 70+ minutes to tell more about backstory of each character even more, I believe this movie could be much more emotional.
Artstyle is great, although the animation seem rough, the lighting and color tone are make up for it. Which help a lot to understand the character's view of the world.
Soundtrack is also great. It fit pretty well with the story, which make the story even more emotional by the end.
Overall, 9/10: for a short movie, It's really great, and I suggest you give it a try. The only thing holding it back is the pacing. It feels like they want to tell more, but they don't have much time.
