Yeah, sorry for that! The difficulty increase indeed, but there is some bug that he doesn't add the bytes it sat to add, and you have to play a lot to pass the next difficulty. Anyway, I got stuck on this bug and couldn't fix at time, but it has more difficulty levels. I noticed also that you could easily leave a virus on the computer and won't change anything, except for the trojan he can shake your camera every 1 s for 3s, but the others was intended to have some skill too. Thanks for your feedback!
