I really loved the art style on this. The vibe was really nice. What song is that? It sounds really familiar but I couldn't place it.
As others have mentioned, I think the camera was a bit jarring. I was getting hints of motion sickness. I also found it difficult to find the ducklings and probably spent half my time just looking for the first one. Making them stand out more in some way would help a lot I think.
Overall nice job and congrats on finishing this in just a few short days!
