Also, the "animals" there are more or less mutated monsters somewhat. Also, forgot to mention this but every time you go up the levels not only does the way of surviving change, but the terrain changes too. Level 1 is just a warm up. (literally) There are no monsters or any entities, just fire, lava, and sharp rocks. Level 2 you have to survive against super fast, strong, and smart "animals" There the terrain is more rigid and mountainous. Lots of hiding spots but the "animals" there are always on the move so hiding ain't the most practical way.
