For me you haven't exactly understood the "regenerative farming" theme, you just followed a "farm" theme. Maybe the futuristic theme doesn't work well with "regenerative". And this theme is not present in the gameplay.
For the season theme, the speed of time is too slow to see its impact. It too sloooowww!!!
For a more immediate fun you may give the player some seeds at the start!
But with a better speed and a better balanced experience it could be fun.
