alot of questions

1) Can't answer it, sorry.
2) Also can't answer.
3) It's just an alarm to remind you that you should go to bed soon.
4) You need to clear the steam first.
5) You need to go to your robot's settings. You can apply one at a time.
6) Nothing, you just continue playing the game. It's a lot like Harvest Moon: A Wonderful Life SE. You just continue the game. It is never-ending.

I can help you with the question number three. You ask about how to gind a big lumber. But what kind of lumber. Does giant wood include? If you got the LV3 axe,you just need to hold the axe longer before you chop a wood.Then the usual wood change into giant wood which the price for it's ship is 250g. I hope you understand! (^_*)

Sorry for mistake of spelling in my previous answer.
CORRECTION:
Gind-find
Three-one and two

Thanks.
