The texts are (finally) done, they are currently being reread. Unless someone finds a major flaw, they will probably be added very soon. All the texts from already beaten missions will be unlocked at the same time, so it may be a bit messy to read afterward like that, but the answers should be there.
There is a third "boss" world as well though, with its own texts. But each one has its own relatively separate story elements, so you don't need to beat it to have the answers from the other two.
Hopefully those will be satisfying enough!
The lateness is on me, it took much longer than it should have to complete it.
I'd be curious to have feedback on the story as a whole, actually.
