I tried to recreate my old fluid sim from This Mine is Mine, and accidentally did better. Hit space to cycle through tile types, and click to turn a tile into that type. The tools are, in order: Air - Empty Space Metal - Immobile Ground Water - Adjacency based-fluidish thing Source - Creates water out of it's nozzle Valve - allows water to pass one way, but not the other Spigot - Transfers 1 unit of water at a time from behind it through it's nozzle The sixth tool is Duck, which allows you to relocate the rubber duck. There is a rudimentary pressure system, in that the darker the water is the denser it is, and high density water tiles will try to defuse density among neighboring tiles. Water that touches the edge will be deleted. The duck does nothing, they're just cool.
