these are very cute and sweet, I'd agree with yazorius that their minimalist nature works very well for the vibe you're going for.
I do agree with the others that the melodies could be a little more memorable, they can feel a little bit directionless and meandering at times.
I feel like there are strong and memorable motifs within your melodies that you return to and iterate on but I think if you used a bit more space / rests in them it would help those stick out and shine more. You do this more in "Let's Catch Some Frogs" and that one I think definitely feels the strongest melodically.
But I do still like what you have here, I don't think it would sound out of place in a cute lo-fi life sim type game as is.
