Bugs
Characters' dialogue starts from the beginning if you move away, maybe make it so the player can't move until all the dialogue is read. Also the fountain restricts movement even though the perspective suggests that it's in the foreground.
Strengths
The art style is really cute. I like the chibi style. The slight moving to imitate breathing during the idle animation is a good touch.
Weaknesses
The walking speed is super slow, I'd recommend increasing the speed. Also the stars are really small and easy to miss, maybe increase the size?
