PirateBattle.io is a fun game where you collect coins and fight other pirate ships.
How to play
You can hurt other ships by shooting them. A small ship without any upgrades can be sunk in about 4 hits, but a big ship with lots of armor can take up to 10 hits to sink.
Get close to the coins to pick them up. When you pick up coins, they heal you.
Move and shoot with your mouse.
To get a boost, use space.
If you have the money, use keys 1, 2, 3, and 4 to make your ship better. You can also use your mouse to click on the "Upgrade" button, but that's not ideal because your ship will move with the mouse.
Have fun and good luck!
