Is it's current price only for episode 1 and other episodes be sold seperately or it's current price is for the entire thing?

From the game's Steam EA Description
What is the current state of the Early Access version?
“At the moment, the first story chapter is implemented to the game. This is already a full-fledged part of the game, almost in the final quality, with all the necessary mechanics to play the game, full localizations into English and Russian languages, cutscenes, settings, optimization and even opening credits.
In the first chapter of the game, there is no personal transport and construction available, because the main character is just at the very beginning of his journey and still does not know much. These opportunities, as well as many other new mechanics, will become available with the next chapters. New chapters will come out as large updates right up to the release. Do not worry, we are not planning any DLCs or paid episodes!”
Will the game be priced differently during and after Early Access?
“After release, the price will certainly go up, as we’ll become greedy and arrogant. There’s a chance that we won’t become greedy and arrogant, though the price will still get higher. However, with the release of new chapters in Early Access, the price of the game will gradually increase.”

Devs sound funny, game looks super interesting and worth it even in its current state... flash backs of We Happy Few in how they handle questions.
