好吧，信息来自此日志的第二段落，说剩下的内容会在下周加入到游戏中，也许是因为翻译的问题我理解错了
Viewing post in Early Access 0.3.3.0 is now Available! comments
Oh, it makes sense now.
Dev wrote that he will add more content to the game in around a week, but then on discord he posted that the public build will be available in ~3.5 weeks.
So this means that new content will be added to the game and only available for paid users until the public build comes out.
I see how you got to that conclusion, I hope it's clear now,
Cheers
