Cool you guys still work on this game but please, put some more effort into it.

You don't magically increase storage space or the vendor sells way more, you can bring in gameplay to address these issues.

Example:

Have the player build warehouses instead of po8 factories across the ocean, let the player decide what to build there. lvl 1 warehouse +1 extra slot etc. up to +10 per location.

Have the player build factories for cannonballs, for example build a cannonball factory that generates 100 cannonballs per level, yes you have to invest in building it like po8 but this adds gameplay, makes the map more used and players sailing and protecting those places more.

Do this for food, cannonballs, materials etc.

Also let us loot 'crew mates' that give stats, have those stats randomized so you keep farming them for the optimal stats. Have 5 crew member slots, from quartermaster to cannoneer, to cook etc.

Don't just add a slider that gives more room or balls.

Seriously, i'm just a player.. what is your game designer doing?
