PeterWade: Some sort of getting started guide would be great. I' ve just tried it for the first time, I've looked at some pretty pictures but I've absolutely no idea how to actually play it. I get that I'm supposed to repair the spaceship, I've got one of the things I need in the inventory (I think) but clicking it, double clicking it, trying to drag it has no visible effect, I've no idea how to get the other bits or how to apply them if I do get them.
I agree they should have put out a manual, however most of the key presses needed I found it did say on the screens.
There are three things you can do from the inventory. Hover over an empty space and you will see the three options and what buttons to press.
Left click to install new technology
Press E to craft
Press X to transport items back and forth between suit and your ship.
To find the items you just need to explore a bit. I found that everything you need was relatively close by. You don't need to walk for hours to find anything early on.
