Now that the game is in early access I plan to now work on the rest of the 1st island.
I plan to implement the following things for next update.

A better looking battle mechanic with character animation.
A farming system.
A mining system only for boulders to gain ore to use with blacksmith.
A quest book for keeping track of current quests.
The ability to transport between areas without having to walk, this will only be for areas that are unlocked.
Implement my types of enemy.
Implement icons over characters that have a quest for player making it easier to identify next quest.
Footsteps and ambient sound effects to help with player emersion.

I currently have no plans to implement a crafting system.

I am hoping to have this all implemented for the end of April.
