Played in the browser through the first combat and reached the loss screen at score 0. The large WASD graphic made movement easy to identify, and the boat and turret silhouettes read clearly against the water. I did not find an equally clear instruction that mouse click fires, so I spent the opening seconds testing input while the turret was already damaging the ship. I would add a persistent first-fight line such as 'Aim with the mouse and click to fire' beside the movement keys, then fade it after the first enemy is defeated. That would preserve the immediate action while removing the first-input guess.
