You can deselect highlighted tiles by pressing Esc, unless I'm misunderstanding what you're saying. I attempted to fix that resource production slowdown bug, but failed twice (I can't grasp how time works in Flash!), maybe I'll retry again sometime.
I looked at the http://www.kongregate.com/games?sort=newest and saw all the Frozen ripoff games for months, but I was left disappointed. Finally my dreams have been fulfilled, thanks Spiry05.
Not for long.
