Obby disappeared into a location called +1 Brick Escape. In it, in order to survive, you need to collect colorful bricks. They are on your feet, so you can run around collecting them. But there is another way - using a treadmill. However, he will not save the hero from the approaching lava. You need to leave, and you will need bricks to make a path for yourself between separately located platforms. Therefore, the more bricks Obby collects, the more chances he has to survive and get out of the +1 Brick Escape location.
