I love it! Very pleasant art style and cool gameplay concept :) I'm sure these points have been mentioned, but sometimes the puzzles have what appear to be unintentional solutions, and it took me time to learn how the mechanics work, but such is a game jam. I think the main confusion I had was with the tall flower- I thought that the stem with no flower was a bug!
I agree with the skipping for the day/night cycle and adding music.
