The objective of this game is to navigate your black square through the blocks, and to the door using the arrow keys. When you get to the door, press the "O" key to open the door and go to the next level. There are five levels. The world will spawn in a sonic boom. Sort of. Try not to touch the blocks. First, click the blue rectangle to go full screen. Then click the green flag to start!
Thanks to @slick300 who helped me at one part.
