A user with a "Hurt" screen.
When you get hurt, the screen of your device turns red for a brief moment. You can get hurt by touchinglava, an angry creature attacking you, or being close to TNT when it explodes. As there is no health in Eden, this only serves an asthetic purpose. However, Ari has stated on Facebook that there is to be a healthbar (optional) in a future update, if not this one. When you get hurt, the avatar is pushed backwards a bit.
