!!!!!VERY IMPORTANT!!!!! If you want the project to run faster, then 1.:click "SEE INSIDE" 2.:click on the "LIGHT" sprite 3.:click green flag 4.:very important: click FULLSCREEN!!! I GUARANTEE IT WILL RUN MUCH FASTER USING THESE STEPS!!! I don't know why, but if you don't follow these steps the project will completely lag! I always wondered what would happen when a laser is in a mirror room... so I programmed it. - w a s d or drag to move the laser - adjust the angles of the mirrors using the sliders - drag the mirrors using the mouse
