Here's Island Quest 0.4
It doesn't require the vanilla game, so you can just download and unpack it.
It lacks a lot of features I'm going to implement but is has base terrain and feature placement.
I indicatd many landmarks (not all though, i.e. I forgot to show the mushroom circle and some other nice features) and resources on map for easier test-play. It's not supposed to be that easy in final version, where you'll need to find a way to understand natives and you will know the map from village elder only; also there's already a map which will be supposed to be avaliable but you should kill a monster to get it. And resources won't be marked either.
For now when you sleep and wake up in the morning don't forge to destroy crates, they have useful items and some starter food.
Also I've made a way to "cheat" - if you dive into the water near your crash site you'll see 3 caves near the coast underwater and they will have a map and an arbalest with 30 bolts. Arbalest may flow up on the water surface sometimes, I didn't fix it yet =). Also bolts are hard to see, but they are definitely there (you'll see a bolt end in the sand).
Try it, tell me your suggestions and test new smithing system (you still can make a hammer from stone+stick, but other weapons should be smithed at the furnace, also you should use "iron ore" near the furnace to get the "iron bar").
You'll have a free iron bar and a free iron ore from crate. I suggest you to make a pickaxe and a spade when you have a chance. You'll need a spade to dig the wells and find some roots/mushrooms (good source of food) and you'll use a pickaxeto mine ore (now you can't get the ore without pickaxe except random "iron ore" items which are very rare).
Also note that it's vry hard to get a rock without pickaxe now. I wanted to add "pain" when you hit the rock, but didn't do it because it's too "hardcore".
Also note that palms now can provide you not only with leaves but with bark too.
I've modded other things like fishing (in vanilla with fishing>500 you stopped gaining starfishes/seaweed but now I made it that with fishing>500 you get your guaranteed fish like before PLUS random chance to get clam/starfish/seaweed).
Play, test, suggest.
