Not long loading but if you using something lagy(like Chrome sometimes or a bad computer)there is a chance that it will take some time to load. When it is ready to play,don't click the green flag that makes every thing start but instead click the green flag nearest to the space bar on the screen. Try to figure out the other instructions but here is 2 of them. 1.C=set volume to 100%. 2.D=set pitch effect to 0%. Don't forget to like and favourite because I worked so hard on this. More than 100 blocks for the main controler-the backdrops.
