I reached the end. That was a long walk, the aiming seems to be slightly broken, as shots don't land at where you're aiming, rather than that, the concept is nice, but I regret not knowing you could sprint.
You can sprint. Press shift. And aiming maybe little bit broken, it works on close distance. But now I'm not gonna work on it because I'm working on new game. Thanks for playing. :)
