GunBoat!

You control a small, heavily armed boat from a top-down perspective. Your job is to navigate through winding river channels, blasting enemy boats and helicopters that appear from the banks. The main objective is simply to survive as long as possible, clearing each stretch of water. You fire with one button, and you can collect power-ups that change your weapon, like switching to a spread shot or missiles. The pacing is relentless; enemies spawn quickly, and the narrow passages leave little room to dodge. It feels like a tense, chaotic scramble where one mistake can end your run.
