This is somthing i've been working on for a couple of days now. The main thing on the island is the waterwheel. Some buttons on the island don't work unless it is on. Some things look different when it is off.(E.g. the water in the porta-potty)Here is the wheel:
I don't care about your page stretch, morons.The consle in the corner is used to control the wheel. It takes a while to figure out.
Here is the whole island:

The door you see down there can only be opened while the wheel is on. When it's on, the waterwheel alternates between different named bricks, giving it a "spinning" effect.
The top:

I know i took this screensot from a very bad place and you can't see much. The orange thing in the corner is a porta-potty, and if you mess with default saves you will know what the other thing is.
It's a blupo brick!Engine room:
Only accessable when the wheel is on.This room has fancy pistons that go up and down.
My room:

You probably won't be able to get in without my help, becuase you have to press to hidden bricks in rapid sucsession to get the door open.
Edit:
I just added this event fishing area at the back. Go there and read the instructions to start fishing. (can also be used for roleplay)


For a special treat, i'll give you the locations of the fish:
You can see these ingame while holding tools anyway, but it will spoil the fun for yourself.Gray bricks are boots, completely worthless things i put in there for my own amesement.
