Dont you just hate it when you find this mini puddle you cant even see and then instantly die? I think they should nerf lava to maybe 50 damage / secound in it. This could ofcourse scale with hardcore and permadeath. I also suggest items that fall into lava burn. Third but not least i suggest fire. First of all add a materials string to all blocks. Those blocks with "wood" would burn. Fire could be started by hand, from a camp fire, from lava or from meteorites. They would burn the item down and then spread to the surroundings. Also trees. This would leave behind ash which could be used as a fertilizer Edit: lava should also leave you burning
