Pirate Fishing

A Baltic pirate, fed up with hipster gentrification of his noble profession, concludes that the real action is in commercial fishing. Pirates being prickly types, however, his methods are somewhat crude: moving the ship with the mouse, upon reaching a desired location the player clicks the mouse to commence the pirate tipping a barrel full of some unidentified bilious black goo into the pristine waters. A simulation of the physical properties of fluids means that the foul brew dilutes as it mixes into a muddy solution, killing fish who swim through it at certain concentration levels much as in the cyanide fishing technique of South-East Asia.

The player's supply of muck is limited; their goal, to net the highest-valued catch of (now-tainted) fish.
