You and probably the other survivors (if they are still there) are the only ones on this hiberworld. We may not know what happened; maybe it was an epidemic, a war that ended the world, or a natural disaster. No matter what ends them, the thing you will focus on is yourself. Of course, you need to go to the tower to find some survivors. If not, then maybe you'll enjoy the last day of your life.

PS:This is not a parkour. It only have a parkour but i wanted a playground so dont expect that yall are going to win
