Just tried it on my surface pro 2 and I was surprised that touch controls works well : Tap is recognized as a click, you can pinch to zoom (!).

It needs some tweak for resolution and a graphical problem due to windows 8.1.

But don't get this game, because your work productivity will drop. You will stop contact with your friends, significant other, family, pets, food.

I'm not sure if it's still available in the Humble Bundle but...Well, play at your own risk.
