How To Fish looks like a simple fishing game at first. Grab a rod, find some water, cast your line, and wait. Then things get a little strange. You can travel between islands, meet odd characters, chase different creatures, and slowly fill up a collection of catches. Some trips are quiet. Others turn into something you definitely did not expect.
In How To Fish, casting the line is easy. Keeping the fish on it is another matter. Pull too hard and the line can snap, but let the tension drop too much and your catch gets away. Once you get used to the rod, the game starts throwing other situations at you. Creatures above the water can be dealt with using a pistol, while underwater targets require a harpoon.
Early quests from Makar and the shop owner give you a reason to explore instead of simply fishing in the same spot. Complete a few jobs, earn some money, and you can eventually afford a boat to reach farther islands.

Every new island has different species, and the bigger catches are worth looking for. Your best catches are recorded in the sea encyclopedia, including their size records. It gives you something to chase even after you have already learned the basics.
How To Fish works best when you stop expecting it to be just another fishing game. The rod gets you started, but the islands, strange encounters, weapons, boats, and rare catches are what keep the trip moving.
