-leftmouse button to walk and attack (to buy stuff at the shop click the shop button near the sign when you are near it)
-rightmousebutton to shout orders around where you clicked. (most used ones are probably GRAPPLE (to get on and off ships/islands) and SAIL to sail elsewhere)
-wasd to move
-spacebar for the menu.
for starters some shipbuilding tips:
-press spacebar to go to the shipbuilder.
-start with just a horizontal line... add some food on it and fencing (under deco, i think you need them so people dont fall off)
-go to the bar and hire a cook
-order the cook to GRAPPLE and he moves on the ship
-he should start preparing food then
-if you get hungry go on the ship and let the captain go to the food automatically.
-that should stop the immediate starving to death problem.
-add more stuff to the ship, walls, backwalls for rooms, mast, crownest on the mast, sail on the crownest/mast, steering wheel, ladders, lamps, etc
-add more food if the other got eaten
-hire more crew
-press space and open the worldmap
-green dots are islands
-big red dots are towns
-flashing red dots around your positions are possible encounters (encounters are "missing" a tooltip what they are when you mouseover them)
-once you clicked a dot you get a route line, if that line goes through an encounter you get an encounter.
combat:
-click something to attack it, or to grapple yourself over
-if in an encounter order your crew to GRAPPLE to board the enemy. (rightclick near a bunch of them)
-pathfinding can be a bit tricky... or sometimes they just walk back to eat... ladders and 2high paths/rooms help a bit.
-some enemies seem to drop coins on death... just walk over them to pick them up (might be an idea to add some sound and effect to this later, imagine super mario coin pickup sounds)
-i think cannons are not working yet (think i never hired a cannon guy yet), and no idea if chests can be opened somehow... but you get some coins for killing enemies.
-if you die... well press space, go back to the main menu and start another round.
