This version of the Viewtiful one features several VFX powers including some that are touch screen specific. You don't need to use your stylus, in fact, your finger is recommended. One of the new powers is called "scratch" and you do exactly that on the touch screen to bring props and production equipment falling from the sky onto your enemies. There's also "split" a puzzle mechanism that lets you slow down time, draw a line on the screen and then rearrange objects on the top part of the split. This allows you to do things like move a safe from a shelf to over your enemy's head. That's a headache when it comes crashing down. The big payoff comes via the "Joe Camera." This move lets you pull down the upper screen (the one that's giving you close-ups of your action on the bottom screen) to literally give Joe a helping hand. You may need to flip a switch to open a door, but you need a close up of the switch to access it. Once you pull the screen down, you can use your finger (or stylus of course) to flip the switch.
