Definitely not! I can't believe it's already Day 3!
After getting some friendly reminders not to leave by the villagers, and realizing how pathetic my life was outside the game, I've spent most of the past few days playing, mining and building. It's so fun I even quit my job so I could spend more time playing it! :)
I didn't realize the game had some kind of sleep detection mechanic built-in. I didn't notice it at first but now every time I try to sleep I hear a weird sound so I've just been going back to the game...I made a lot of progress though! I think soon I'll be unlocking the next area!
