Hey, looks pretty sweet! If you need/want some help, either in general or in actual turning this into a full game, shoot me a PM. I've got about 6 - 7 years of experience in Unity, and I wouldn't mind having another project to work on.
And to the people saying you don't have to touch the code to make something of it's "too easy"... You can make maybe a simple level and a non-animated character from the default files. I was working on a project with my friend, and we got really in-depth with the programming. He even made some of his own .dlls, lol. Sure, it may not be Unreal, but that's no reason to beat up on it. It's still a great engine. It's just because it is easier to get started with, many people start, and few get far. Thus, it makes Unity look lame.
