Vessel is built on an optimized liquid simulation featuring flowing water, scalding lava and steam, reactant chemicals, glowing goo, the mysterious 'protoplasm', and more. Each liquid has unique properties and mixes with other liquids for dramatic effects. Bring Liquid to Life – Interact with 'Fluro' creatures that are formed entirely from simulated liquid. Each retains the properties of the liquid they're made of, giving them the ability to melt, reform, absorb, explode, and more. Unique Puzzles – Solve puzzles by combining the unique behaviors of each creature with the fluid they're created from. Every aspect of the world is physically simulated, and all puzzles are based in the liquid simulation. 2D/3DHybrid Art Style – Explore a world of fantastic, detailed machines and strange, wondrous environments. 2D hand-drawn textures combined with 3D normal maps, lighting, and depth creates a unique, other-worldly look to the visuals.
