I am a very avid and longtime player of this flash game on the PC, and I have to say, there are many similarities. This game via iPhone gives me the same excitement that I get when I play it on the computer. The towers are perfectly matched (minus boost, which could be added) and the sounds and speed are great. The upgrading of towers doesnt take time like the computer version does, which I like. One of the things I dislike is how tough it can be to place the towers in the right places, which is its only real flaw (a major one I might add). Maybe a zoom feature could be added to ease placement, similar to that of Words With Friends. Also, a grid would be nice for ease of placement. Otherwise, I love this game and recommend it to be bought!
