Very cool concept. Games with fast moving cameras like this one are a bit hard for my eyes but the execution is well done. Would be nice if at each intersection the starting direction that I move is always the same. For example, the selected direction is always the direction in which I came only because a few times I went the wrong way and wanted to quickly return from which I came. Sometimes the direction I came from was the one chose but at other times it was not.
This would be a sweet mobile game where I tap the screen to move. Nice work! :D
