Please add achievements like "buy 5 decorations" for 1st star, "buy 25 decorations" for second star, and "buy 100 decorations" for 3rd star. The reward should follow the existing achievement in terms of gems. Also, that means more decorations would need to be offered, like a lake or wishing well, etc. The wishing well could also like give out cool things if you spend gems. Those cool things would not be available to buy with elixirs or coins; only through the wishing well.
