You can advance to the next level when you have filled the bar required in that level. Once all switches are turned off, the game is over. You have 10 lives, in a form of on switches, in each level, and it will be reset when you advance to the next level.
There are words coming down from the top of your screen, and you have to clear them by typing the word and press Enter or Space before it reaches the base. This game is adapted from the popular Facebook game called Typing Maniac.
