The concept is translucent at best. Maybe a simplified tutorial could help; however, I think that the idea you have envisioned is greater than the capability of the programmers and/or the engine you decided to use. The repeating aspect is limited by rigid planes, so you can't have it repeat in any direction you look, and that alone is a game breaker. It's like you are trying to mimic Portal on a grander scale; however, Portal works because the mechanics of the portals being placed on a defined plane makes it intuitive, where this is messy. Gravity becomes a convoluted mess here, which further frustrates the experience because of the repetition being so limited.Walking on the gray areas seems like a forced solution to not being able to flesh out your idea of a game into an actual game. The concept is interesting, but what you are tying to achieve would require a lot more advanced code, or more powerful engine than Unity. In any case, I will go back to dreaming I'm Batman in my Underoos.
