I really like this game, the How to Play is clear, the gameplay is good.
Where I think it needs the most work is the UI, I would love to get in and modify it myself :)
I'd consolidate it all to the bottom of the screen, I'd use coloured text to make it more intuitive.
I don't play a lot of RTS but I'd play more of this if you make these changes.
You could do some really interesting things here too, like if you chop down trees or mine too fast the storms get stronger...
