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.

Oh, you made a whole soundtrack, that's impressive! I really like the mood of it all. I agree with anipatok's comment regargind the similarity of the track and Error404 about the melodies. One trick to fix both problems could be using a leitmotif. So you can make a melody that will remain in the listener's head and use it in tracks that are different in mood, tempo, instruments, etc. but remain recognizable as part of the same environment. Keep going like this!

The last music made me close my eyes for a moment just  to listen to it and chill. A tip you should know is to check if your melody is easily singable or "hum-able", so that it's easier for people to remember it. Very nice OST tho!

Cute, light, very minimalist, but does the job perfectly. A complete OST, with a chill vibe, totally in the spirit of what is expected.

I think your heart is at the right place :D I like the happy tone these have and I think these are musically not bad at all. The first three tracks sound a bit too similar to me but the last two are pretty good in that regard. Nicely done, especially with beepbox!
