Bad

in the standard viewing screen, you can;t see the full play area. you can scroll from top to bottom, but you can't use the mouse wheel during the game, you have to use the scrolling on the right side of the screen. make it to where you can see the full playing area, or inform the player of the optimum way to view the game, full screen, ect. I had an issue with placing the turrets due to not being able to see the full playable area. i ended up placing them in odd places because of this and it affected the gameplay because of it. ultimately, i really didn;t enjoy playing this game. having one button for all the commands, movement, firing, and placing turrets can work well, provided the player can see what's going on with the rest of the screen. otherwise, you run into the situation that I had and you can;t see where one wave ends and the next one begins, nor when you can place turrets. I might give this another chance if the play area issue was fixed and one can see the full screen without having to scroll during the game.
