How the boss works: To start, you will be unable to use your sonar, as 15 will overload it with energy. tiles will have a chance to become electrified for 5 seconds (5% chance), clicking an electrified tile will increase the voltage meter that will be shown where the sonar is by a small amount, if the voltage meter fills all the way, it's game over. 15 has 3 different abilities: ability 1: 15 will occasionally shock the area around itself in a 5x5 radius, if your cursor is anywhere in this area, you'll be stunned for 3 seconds and the voltage meter will increase by 1/5 ability 2: 15 will shoot at your cursor with it's blasters, if hit, you will be unable to click any tiles for 5 seconds ability 3: 15 will have a chance to spawn a large electric mine, this electric mine behaves exactly like 10, bouncing around the screen with a timer of 10 seconds, you must click the electric mine 5 times before the countdown reaches 0 to disarm it (clicking it will not reset the timer), if you fail to do so, the electric mine will explode, filling the voltage meter up by 1/3.
