I agree with you that the conflict in this project was not very well resolved. A while back, I made a cozy game (for the #69 GWJ I think) and received some criticism regarding it being too "rushed," so I tried to make the freezing/snow mechanics as light as possible.
Basically, what happens is that plants that are on snow do not drop fruits. I tried to explain it through some tooltips, but I think I lacked a bit of objectivity in this regard. Other users reported similar problems.
Thanks for the detailed review, I will take everything into consideration for the upcoming projects 😊
