Harbor Defense
Harbor Defense is a defence game with one job: stop the enemy ships reaching the harbor. The tiers change how the assault arrives rather than only how fast — Easy sends slow waves, and the harder settings compress them, so the question shifts from whether you can hit a ship to whether you can hit enough of them before the next wave overlaps the one you are still fighting. Free in the browser, no download, no signup.
