-Torches on the wall: I think it would be a great idea, a stand to put torches on the wall or something, you also have that supplies it with coal or wood to keep it on.
-Character Customisation: more types of clothes would be a great idea, helmets, hats,shoes,backpacks (expanding the maximum number of items you can carry, but leaving slower) and watches. The clothes could also rip or ruin with time and with the amount of damage you took using it (you can fix it).
-Weapons and Items: A sniper, would be pretty cool, but you could not learn to do it, only catching the plane, the same with the ammo.
A knife, with it you could get a larger amount of loot of animals and do more damage than people in the pickaxe or hatchet.
-PLEASE add a command or something like that to someone is allowed to open the door with it, with that, he gets a key (I think it would be cool) and he have to keep with it to open your door, and if someone else kill him, he can grab the key and open your door.
-Bikes, cars, speedboat would also be cool, but I think the map is still very small.
And speaking of the map, a compass would be nice (you need to find it or make).
-Other islands, you could go on a boat or swimming (with special clothing allowing breath underwater and swim faster). On the way you could find other animals such as fish, sharks, alligators, and others.
