Portal or not? (Q.U.B.E.)

Well, Yes,it's the same puzzle.But I liked it more than portal.

Of course similar. Only pure white space are worth. But the gameplay in Q. U. B. E. is quite different and more diverse.

Similar only in principle and a bit atmospheric. And the gameplay is different,and puzzle others, and overall the game its like dissimilarity is no less impressive that Portal .

I would add that this is the portal light.
