Awesome work, guys!
Have you considered enemies in the game?
Zombies are planned, but dragons would be perfect in the mountainous areas, i'll probably use that sprite.
Anyway, for the game, boats!
They work great, although they're not "buildable" like in Cow RP [As in, the boat would be four tiles wide and you'd be able to walk on it while it was moving for the cost of buggy stuff] But they work great for transportation!
And for people how wondering the game is going to be, this is a moderately-sized island i made in a few seconds.
And this is the entire map.
The island i mentioned is in the bottom-left, not the big spawn island in the middle.
Now that's pretty big!
