Name the video game

Answer

I think the answer is:

Portal 2

Turn the tap and open the valve

Not 100% sure what this means, but Valve is the company who published Portal 2. Turning the tap could refer to the new gels which kinda look like they're coming out of faucets.

You won't have to face her by yourself

Unlike Portal, when you face GladOS in Portal 2, you have Wheatley alongside you.

Something new comes out, oh it's blue! Go for a bounce, you know you want to

One of the additions made in Portal 2 are various gels throughout the facility. One of them, the repulsion gel, is blue and allows you to bounce around.
