Player level is a game mechanic in Maritime Kingdom. It acts as a measure of progress which rewards the player by unlocking content as they play. Certain Player levels unlock Buildings, Decorations, Ships, and Ports, however reaching a new level may also reward the player with a small sum of Resources or Trade Goods, especially Gold and Crystals. Every action in the game, whether it's collecting Gold from Residential Buildings or defeating Pirates, gives the player a certain number of points towards their Player level.
