buy guns with coins (shown in bottom right) and click to place them, then point the mouse in the direction you want them to point in and click again. The gun will point in that direction forever (unless it is a swivel gun which always point towards the mouse) until you win or sell them, you sell them by hovering over them and pressing space. You will receive 50% of their cost for selling them. You can also upgrade guns (added in 1.7) by hovering over them and clicking. This will cost however much they originally were. To start a wave, click the box with an arrow in it, if you do, dots will come from the top left and go along the trail until they reach the end, if they do you will lose life. (shown in bottom right.)
