Early Access.
The game is not completed. Rather this is one of the final, if not the final early access build before the game enters its 'release' state. A game can be in its 'release' state and still not be completed. You can find several such examples here already. "Final EA" doesn't automatically mean "Game done".
To clarify: Final does not equal "Finale".
Far as I can tell, the developer's native language isn't English, and as such, some things regarding syntax, or phrases that are common in their language (I believe Spanish) don't translate well over to English.
