How do you beat the Crimson Room game

First, look under the Pillow. You will get the Key(#1). Look at the curtain. Click it to open it, and get the Key(#2). Keep clicking the curtain until the Ring(#1) falls. Pick up the Ring(#2). Next, click the Bowl on the Dresser and get Ring(#2). Use the Key(#1) and Key(#2) to unlock the bottom 2 Drawers on the Dresser, and collect the Power Cord and the Mystery Box. Open the top 2 Drawers. These 2 items, the CD Case and Memo (which is a URL), are unimportant to escape*. Look under the Dresser by clicking underneath it, then collect the Cassette. Next, look at the CD Player. Connect the Power Cord by clicking on it then on the CD Player. Click the Power Button and open the CD Player. Collect Key(#3). Once again, look under the Pillow. Click in between the Mattress and the Headstand and collect the Metal Bar. Click on the Mystery Box and place Ring(#1) and Ring(#2) in the correct Ring Holes, and the Metal Bar in the long, rectangular space. Open the Mystery Box, and place the Cassette on the spot where the Cassette Holder Bars are sticking out. Now, you will see that the Mystery Box is really a Cassette Player. Watch the Dance, and near the end the Boy will point to a +. Keep your Mouse Cursor on the Middle of that +. If you accidentally miss it, or mess up, you can play the Video Dance again. Now, click (or double-click) in the Middle of where that + was. You will see a Safe. Click until the Code says 1994. Now, put Key(#3) into the Key Hole, and get the Screwdriver. Get the Screwdriver, go up to the Door, (which you recently could not open) and click on the Screwdriver, then click on the side of the Door. The Doorknob will fall out. Click the Door, and it will open. Congratulations!!! You've escaped the Crimson Room!!!
