i wanted to expose more because a lot more people got into this space, especially the last year. If we talk about inspiration of where we got inspiration for puzzles, is if you look at things like city f which are very different in nature but also focus on hacking am and exploiting systems.

I think it is a very funny to get into it. And i think you you might have a good fun that this sometimes is similar to what you would see problem in university, but in in a different sense.
