Pirate Dodge

You've got a small boat, a river full of junk, and pirates who really don't like you. Switch lanes to get past rocks, islands and the odd kraken tentacle. Pirate ships are the real problem. Red ones shoot at you, black ones swerve into your lane, and teal ones fire fast. Shoot back, grab the coins and map pieces they drop, and save up for a bigger ship with a better cannon. Runs are short, so it's easy to say "one more go" and play for an hour.
