Can I build a multi touch app for windows 8 with Unity 5.0?

I've been working on an air hockey style game, and I'd like to have two player capabilities on a single screen running Windows 8.

So far I keep having issues of the multi touch inputs merging their vector2 positions together.

Without getting into the code, I just want to check if this is supported, and if so, are there any restrictions or settings I need to be aware of? For instance, do I need to set my build mode to Windows Store?

Edit: Beyond creating a windows store .sln project, will I be required to submit the game through the windows store in order to run it on another system? Or can I generate an .exe that I can manually transfer to another computer?

Thanks in advance.
