You know I can see this game growing into what millions of people will want to play. So to help out, I got a few suggestions of my own to help you all out, and expand your game content.
1. Make it so that we can dive into the water so we can see things like coral revives, spear fishing would be cool as well.
2. Add a sail and steering wheel to the game, so that players will have an opportunity to ride the raft that they have built along the may miles in the ocean.
3. Add some land content to the game, not much but just enough to find things like animals, and bananas on the trees.
4. When land content is added, make it so that we can take those animals back to are raft, and breed them, for thigs like leather and food.
