A satisfying tower defense! I enjoyed building up a solid wall of beehaves to protect my army of money making farmers, so that I could eventually defeat all the invaders with the power of tomatoes! :D
Very solidly made, the only slight thing I noticed is that; if you click to place something which you don't have enough money for, it will still remain unbuildable once you can afford it. The icon remains highlighted and you have to un-select, then re-select it to place the tower down. A very minor thing over all.
