Hello, there was this mini-game on an old shutdown server called "Inferno Rush". I have put a video of it below. The server which hosted this mini-game was called "Multicube" which is now shutdown. If cubecraft took this mini-game idea and created something similar to this, I think me and many other people would love it. You could change the name, because you don't want to copy everything about this old mini-game. Thanks
