This game has to have the biggest bunch of whingers in it.
Good grief, the chance to get something for nothing, except the ability to click on the mouse.
Instead of whining about it, come up with some ideas how to improve it, the Devs occasionally listen. Don't leave all the thinking up to others, come up with some ideas yourselves.
Oh by the way devs, the new defence items were great, now we need new offensive weapons to counter them.
So next levels, something to crush and burn, would be well received.
