If you like this game, you can buy a standalone version. It will at first be the same game, usable "outside" your web-browser, but it will soon be updated to include extra functionalities and content (that are not fitting in the online version), like the possibility to save (very soon), different screen resolutions and full-screen support (very soon), a new activity during conquest (soon), more gfx (continuous addition when I will get time), multiplayer (when I have enough time), level's edition...
It mostly supports me to work more on it :)
The standalone game costs 5€ (worldwide), and for this price, you get free updates for the whole life of the first version. As you basically pay for the effort needed (here 4-5 months of work full time), the price of the second version will depend of the extra work needed.

If you have an interest in modding and/or enhancing the game (code, gfx, sound or music), you can obtain a standalone version by your contribution (see the "Dev" section).

To thank the first buyers, I will create a special boat for each, just precise the name in the "special wish" text area. If you want any other thing, please ask for it (eventually by mail, see "contact" at the bottom of the page), I will see what I can do.
