Following an accident involving a scuba tank, hundreds of blowfish have been launched out of the water. It's now up to the squids to take matters into their own tentacles, and set up a rescue mission to bring their friends back home.
Use your ink to move the fish around, while avoiding spikes and other traps. You will need both skill and intelligence to pass the 100 levels of the game, and bring the blowfish back into safe waters.
The fluid simulation of the game is computed by actually solving the Navier-Stokes equations, resulting in realistic liquid movement.
The game features dozen of different elements that the player can interact with, like canons, lasers, switches, moving blocks, etc. Each chapter takes place in a different environment, so that the game never feels repetitive.
Most of the graphics are generated procedurally, so that each time you play, the levels and colors will look slightly different. It also ensures that the game is less than 5 MB in size.
