Here is what I think the items mean/do
God Mail: It is like a spam email to the computer and whoever you use it against sees it as their top priority to check the mail
Hydra Heads: I think this is just brute force, trying again, and again, and again, until it works
Melted heart: Appeal to emotion, if the entity seems like it would appeal sensability or lies then this will work
Rootik: This is telling it you're inside and it is fruitless to try to get it out
Logic Bomb: This is telling the cpu system something that doesn't make sense, something that makes it's functional code unfunctional, It breaks it
That is my Interpritation at least
Hey mate, wow, I didn’t expect my game to be analysed in such detail. It’s really nice to see! But I’m afraid I didn’t put that much depth into these elements myself, although it seems I really should have. I was just trying to draw icons for the most popular programmes used by hackers, like Hydra brute force or the Heartbleed exploit. But I liked your ideas so much that I’ll definitely take them into account when I’m finishing off this game)))
Thanks for playing it, and I hope you enjoyed it!
