Down, Down: No matter how good it is... it's not Portal and there is just no getting around that. The gaming world waits for the next chapter of that story, and no matter how glad I am for the fix I am jonesing for, it's just a stepping stone on the way back to Aperture. It's a sweet, responsible, transitional girlfriend of a game, and I hate to break its heart. Still, when the real deal comes calling I'll be off.

Left, Right, Left, Right: Switching dimensions uses the shoulder buttons, and is such a snap that you'll be an expert in minutes.

If you're having trouble in the game it ain't the control's fault.

Derp reminds me of Early Grace, may his cheesebrained soul rest in glory.

Just because first-person puzzler is more or less a one franchise show doesn't mean that a gamer can't fall in love with a little spice on the side until true love returns. If you want to test your ability to think outside the box, then download Quantum without hesitation. If you want to mindlessly shoot things then go elsewhere. Mad geniuses only need apply.
