Hey ! I replayed the game and the music fits the whole cute aesthetic ! Your instruments selections work's really well too.
If I could give you a couple of tips from one composer to another would be to make use of the expression cc into your D.A.W. For exemple the flute works really well but you can hear when the note is turned on and when it's release.
To give each note more smoothness, research the expression or the volume controller on the virtual instrument that you are using and make the note fade in and out just briefly.
Another thing I would've loved to hear is some longer loops as to avoid too much repetition, in my opinion the one in the house could use some more time. Or you could also make short segments like what you already have, that are very similar, and play them in loop in a random order.
Don't get discouraged ! Your game sound great and it's only the opinion of a dude on internet.
