I have a version 2 that fixes most the issues you have highlighted, this is now live so check it out.
But the art style is the art style...
:)
Checked out the new version and spent over an hour playing it... though I don't know exactly since integration with the itch app is still missing so it doesn't record my play time. The name of the app is fixed but that's the least of the unfriendly things it asks me to do to play it.
The lack of save is disheartening and the sudden jump from sapling to huge shading broadleaf in one season is odd - run out of time I guess? Though at least the option that was broken is now fixed.
Will give this another try in time but I've not the time for this right now, sorry.
Maybe once it is a more mature game.
