I'm only just starting to fiddle with Construct 2, but I wondered about creating mobile games. Usually, the touch screen itself acts as the buttons, using multitouch, and also allowing for held buttons. Example:

I'm looking at a platform game which can run on mobiles, and I want to have two buttons, which you hold down (so "on clicked" won't do the trick). The "up" button allows the character to jump vertically, and the "right" button moves, er, right! Ideally, the longer you hold the "up" button, the higher the character jumps.
I know there's a multitouch plugin, but I'm not sure anyone's using it like this?
