Thanks :D
Yea, the goal isn't clearly told, wanted to do a full tutorial with actual dialouge, and getting taken trough the different systems, but managed to get so sick i was rotting in bed for a whole week unable to do anything
If you want to give it another shot, the goal is to craft a space gun before the alien reaches the planet you are on (you just need to have it in your inventory when the timer on your current planet runs out), you can place down the crafting bench, and scroll to it's recipe to see what items you need to gather
And for using the ship, you just need to be near it, then open the map (M) and left click on any planet/moon to travelt o it (you can also right click to see what resources it has, and it's description)
(Also for planets/moons without an atmosphere you will need a helmet in the rockets inventory, you get 1 at the start, then you can craft more)
