My version of The_Evil_Pickle's various tiles mod. Improved graphics (although some tiling errors still exist), and lava now has many more uses, such as....
-power generation
-a deep-quarry like system
-a more powerful, lava-containing fuel (+175% acceleration, max speed boost)
-a lava-powered furnace (that currently isn't compatible with any mods)
Also, when lava is used as flamethrower turret ammo, it deals 250% more damage.

However, lava-fish still exist...
