I think you’re getting tripped up on the wrong expectation. Maybe just because of the way this thread was bumped and we had a day to speculate wildly—optimistically even, if that’s your thing.
But this isn’t a new Portal game, and no one is going to be confused about that if they just see it read about it through the normal channels. It’s a Portal “flavor” of an existing game.
Ha, yes, I can’t see any way this could possibly go wrong. Anyway, I have officially lost what little interest I had in this game a couple hours ago, I’ll probably pick it up in a Humble Bundle in a year or two.
