Fishing Master

Arcade fishing of the cabinet kind: you do not cast a line, you aim a cannon at a screen full of fish and hold the trigger. Fishing Master pays gold by species, pays more for a streak, and spends it on cannons that go from a single barrel to a four-shot spread. A hundred levels climb in difficulty and each one ends with a boss worth a small fortune if you can keep it in your sights. Progress saves in the browser, which matters in a game you play in short bursts.
