Ever tried an underwater physics-based shooter? Jump into your yellow submarine, and save the rare plankton from hordes of nasty marine predators! Use giant bubbles and shockwaves, upgrade your equipment, send enemy shots back, push monsters into deadly whirlpools and more!
Fight 20 different sea creatures through 15 levels of increasing madness, from the sunny littoral to the darkest hadal depths!
Are you strong enough to challenge and defeat the three evil bosses of the abysses?
Click on the submarine and drag it around to move, or use the arrow keys. Shoot stuff with the left mouse button. Once you've bought these weapons, hold right ctrl to blow a bubble, or press right shift to launch a shockwave.
