I just can't do it anymore...
Unfortunately for me, the first screen I saw when I started this game recommended that I use a gamepad. Well, that wasn't an option for me since I didn't bother to bring my gamepad along for my trip (totally thought about it too). "Keyboard can't be that bad," I said and although it wasn't for the the first couple of chapters (albeit I died countless times), now I'm stuck on chapter 3 (sad, I know) and my patience has gone out the window.
So the moral of the story is, always be prepared. You think you don't need it? Well let me tell you, you do need it.
