This is nothing
I like to figure out what is going on, solve it, find ways to beat it. I think when people are under some conditions, their behavior starts to change from what they are used to. Most people are prone to do the things that they think they never do. However, I think we all do it but not to that extend, we are generally not aware of it that much since it is not that obvious. This concept shows some aspects of human nature, that is not so apparent to all at first glace imo.
I thought vault(youtube series, their first product) was very similar to cube, they were in a cube so it cannot get more similar to that
Circle is like cube also but it is a circle
