Stop the dots from getting to the other side of the map! Once a dot exits the map, you lose a heart. You start off with 20 hearts. Still reading? Good. You don't want to miss what I'm about to tell you. You start this game off with 200 dollars. Use that money to get some machines to stops the dots from getting to the other side of the tower. After a dot is killed, you get some money. Use that money to buy more machines. You can add as many machines as you want. Remember, after you place a machine down, You can't move it to a different spot on the map. After each wave is done, the game pauses to give you time to add machines. Remember, you can add machines during a wave. Remember, each wave is harder than the previous one. Good Luck!!
