Awesome idea for a hacking minigame! Copy/pasting variables into a decoder and following basic programming logic is a brilliant way to represent hacking, on account of it's, you know, actual programming. I did get tripped up on the final level because I didn't know what has adv_com was referring to until the level reloaded with the adv_com. I feel like in order to get this idea, you have to know programming, which by the nature of this being a game jam most of us de-facto do, but this might be harder to grasp for a larger audience. Even so, this is fantastic! I hope you don't mind me taking inspiration from this if I ever do a hacking game, because this is awesome.
