maybe some improvements on the UI
There's a wide gap between elements and effects (nature / what it does, farmer / items, You / items) This makes it difficult at first to understand theres a link between them. Took me a while to get that my actions were on my side..reduce the gap and or link them in some kind of frame. Then the season's effects are presented differently with that big X, this is probably a multiplier, kinda confusing a little.
I played flower action never saw any.. I guess the proper effects weren't in place. maybe some representation of the current global water, and other parameters would help understand, like gages or something. Instead of trying to sum up effects clicking icons we'd have a clear view right away and might try to understand whats affecting what.
The most important thing you need are small sound effects and a nice music (changing with seasons) just search for some on freesound.org. This will help understand the flow of the game... click on my action is different from click on other effects.
Hope this helps!
