Narrowboat Simulator a simulation with some game aspects. You control one of Britain's typical narrowboats in a 3D environment.
During the game you'll have to perform some simple tasks. To advance you'll have to collect "Canal Karma" by displaying your navigating skills. Speeding and behaving like having a ride on the dodgems is considered as bad karma and will reduce your score.
Having completed the tasks with a high enough score will allow you to cruise freely.
