Sorry to bother but , I don't know how to play the game , I don't understand how to pick up stuff or anything else . Can you please tell me?
Hi! Sorry about that! In the pause menu you can check how to play and what do you need to do next.
Anyway, the first thing you have to do is looking for your backpack, once you find it (it's close to the ship) use left click to grab it. In the pause menu you can always check what's the next thing you have to do.
Once you do the first missions there is a crafting table in front of the ship (not that close), there you can craft new things like axes (to get wood), pickaxes (to get stone)... and many other several items. Some of them are just decoration for your base, others are necessary to progess in the game story.
Just follow the steps that the game tells you (you can always check it in the pause menu).
You probably couldn't interact with anything because you didn't pick up the backpack, which is one of the first missions and you need to do it to keep playing the game.
Good luck with it!
