In the game Visible 2, play a secret agent that is sent on secret missions. First, you have to learn how to move your agent. Use the arrow keys on your keyboard to move left and right. Push up to jump. To clear a level, you have to make it to the portal that's on the screen. The portal is bright green and glowing, so it is easy to find. You can also run up walls, so you don't always have to try to jump to the top of the wall. If you get a running start towards a wall and jump, you will be able to climb the rest of the way.
