The Entropy Center is much more like Qube than Portal. (Especially in terms of its quality. And the more mindless back and forth dialogue. Versus Portal's morbid wit.) Still has bugs and flaws that I'm sure will be fixed with future patches.
But the thing is...this game is filled with non-puzzles. And no, I'm not talking about the trial-and-error 'run through the crumbling level' sections. In fact, that's somehow the best part of the game. And no, I'm not referring to the lack of challenge either. (Though this game definitely needs harder and more open puzzles.)
No. I mean the cube and switches puzzles ala Qube. Except, EVERY single trick this game pulls is, "Here, do the whole puzzle with what you can see. And Ah, HA! There's one more hidden switch at the end. Do the whole puzzle over again." (Rinse, repeat, fall asleep.)
Halfway through it in one session. Hope to finish the rest later. (And now I'm concerned that it won't even lead to anything worthwhile either. Since the dev on reddit acknowledges "his ending might be controversial." Yeah, buddy. That means its sequel baiting, or it has an ambiguous and unanswered plot. And those things are controversial for a reason. They suck.)
