FIX：
1、We fixed the problem building parts window cannot fully be displayed.
2、We changed the textures size limit and compress method, it helps optimization of RAM using and FPS performance within almost invisible visual performance loss.
3、We unlocked the rotation lock during the continuous building.
ADD：
1、For in-depth building players, we provided a light-physics mode, which helps to build large scale warships with higher FPS (Physics performances improved, rendering efficiency optimization is ongoing ).
2、Add three ranged weapons:
（1）Oil tank thrower
It can throw an oil tank. The oil tank will explode while kindled and will make oil spread on the surface of the sea. Oil can also be ignited to deal fire damage for a while.
（2）Charge ballista: Pressing down the control button to charge, it accumulates power and range over time.
（3）Fire rain: Throw a bunch of arrows, which can explode in the air and create an arrow rain that deals fire damage for a while.
3、Add several new scenes.
4、Open ocean functions finished. You can visit other players' ocean for high-profit trading and salvage collecting.
Plans in the future:
We plan to create more contents for the open ocean (buildings, events, etc.). Also, we'll add more levels for the single-player mode, and tutorial content optimization is proceeding.
