[FREE] [Steam] Odysseus Kosmos and his Robot Quest: Episode 1

yeh ,it confuses newcomers ,it's been like that for a while now.

Well, this is the same as the old shareware model.
So many games were first episode free or bundled with a magazine disc.
You then bought the full retail version to play the entire game, it's hardly what I would call a deal.
It's especially crappy that the dev would have a separate appid for this instead of providing it though the same store page as the full game.
