help screen does not mention ESC button.
I think ESC is a key button to cancel operation before times run oun. (avoid being traced)
Second thing, trace bug:
hack first server, double click it (bounce)
Now, trace timer will start. (you will gain more tracetime sametime also)
Wait until timer is 5s
Then unclick bounce, you are immediately traced. (you can heard double ZERO..)
In hard difficulty, It feels like you need only double click any server two times and you are traced. (lose flawless)
A bit off there buddy
Space = auto target the local client aka stop trace.
So when your done with a thing, esc followed by a swift space
Also the second, regardless of double click or single click, you click on any client other than local host, you start getting trace timer!
