Floor is lava play online

In a land of volcanoes and extreme heatwaves, there are human survivors. They try to find food and place to stay where it's not much land, but lava all around. Vicious animals always try to steal your food, mobs try to attack and rob you, and all you can do is run, climb, jump and use ropes in a land where you cannot touch the floor (well, most of it)
