Thanks for your feedback!
I didn’t want any system to work for too long, as that would make the game too easy. Someone suggested adding some form or random events you’d have to deal with, I think if I add those I’ll definitely need to make the consoles active for a longer time.
As for the instruction screen - you’re probably right. I’m considering replacing that with a list of hackable systems and description of what each of them does. I’ll also add a more visual description of the hacking process, once I upgrade it.
