Click to shoot the blue bullet, and press space to shoot the orange bullet. Use WASD keys or arrow keys to move. When you shoot the bullet, make sure it hits the white part.
Since I was doing pen art for a while, I decided to take a break for a bit. The portal is a way of teleporting from one place to another. When you are done shooting on the walls, therre will be some portals. If you go through one of them, you will teleport to the other portal. Make sure that you get away from the portal fast enough after that, or else you will be teleported back! Portal: http://scratch.mit.edu/projects/23047781/ 7/22/14: ALREADY one love from @leszpio! That was quick!
