Oh I like this one! The addition of the portals was a great idea, and being able to switch between the two pieces and control them independently felt pretty good.
My only thought it that it might be more intuitive control-wise if the blue piece had its jump button be the down button since, even though you're jumping, you're going down on the screen. But I got used to the controls well enough by the end, so that's just a little nit-pick
