I actually beat the earlier version that didn't have sprint (I am so OG) but having it is alot less rage inducing.
It's a good game, and when I first played it I was all "oh shi- all these people how will I ever find-" then I noticed the yellow headless chicken panicking in the crowd. If you could make the target blend in more with the crowd to start, I think it would add alot to it. That and the ability for the bad guy to escape.
