I cannot, for the life of me, remember/find a game I played last year.
I don't believe it was on Armor Games. It was a nautical game. It's a down-view / birds-eye-view game. You control a ship (either naval or pirate, not entirely sure) with the arrow keys and waves of other ships come at you (from the top of the screen). You have to fire cannonballs at these ships while constantly moving around, avoiding the incoming cannonballs. I think after you destroyed a few normal baddie ships a "boss like" ship would appear which would take several more cannonball hits to sink.
I'm sorry I don't remember any other details. I hope someone knows which game this is! Thanks in advance
