Damn. I loved this. Great atmosphere and pacing. The designs were simple and cute and the backgrounds were well-made and intriguing. Really good ending too with the future vision as well as the bird at the end.
The only noticeable issue I had with it was some of the sound effects didn't quite line up with the movement of the characters, like there would a rummaging sound that lasts a bit longer than the animation of the shrew's actual rummaging.
Overall, I really dug it.
