This is so CUTE!
Love the chill music as well. The characters are very well thought-out, and the environment design is excellent!
It's very relaxing, and I love the different parts and costumes in the designer :D
I think with a bit more animation it could be even better, for example: the character movement could be animated, not necessarily with more frames and their legs moving, even just some good old squash & stretch can add a ton of life!
Also just flipping the sprites based on the movement direction could make it feel more natural :)
