You can create your own level by clicking on one of the blocks in the box. Then press space to place it. If you want to delete the item you are holding put it over the trash. If you want to create a new level just click clear. Once you are done click start to play your level. You are the color changing block. Go left with the left arrow key, go right with the right arrow key, and jump with the space bar. Blue is bouncy. Yellow is speedy. Red is lava, DON'T TOUCH LAVA! Black is just a regular platform. And you have to get to the green portal.
