click start then click the tower. Enter in the number of which box you would like to go to. the aim your mouse and that is where your blue ball will shoot. there are two towers to pick from. Red and blue. The only difference is their color. They cost 50 dollars each. The bomb costs 100 dollars and sometimes works (I think?). red tower shoots the red ball. When the dots hit the edge of the screen they will go back to the beginning until you kill them. This has many glitches just so you know.
