I bought this game immediately based on my enjoyment of every other game by this developer. I wasted my money. I've tried for 3 days to play this game, hoping it would improve before my eyes, but alas, its not going to happen. Strategy is non existent - weapons graphics are not different enough from each other to easily identify - no easy, medium, hard levels. And the track is ridiculously short and boring with no overlap spot to strategically place the first weapon when money is tight. Tower placement is haphazard and ineffectual. There is no indication of which direction the next wave is entering the track. I am actually deleting this game entirely as there is no hope for it. I certainly hope this is not a new direction for this developer, but maybe an old game re-issued after the success of the previous games.
