A gauntlet mode for tilted where the level is continuous and you only get the marbles that start at the beginning of the run. I have thought about this in two ways: A run with levels where survivors are maintained over the run, but nobody else can join; a continuous level where the tiles evolve over the run. With the latter, if the tiles could de-spawn and spawn to maintain a consistent number of tiles in existence, it could help with minimizing performance issues.

I think this would be an amazing challenge and fun twist on the mode. This idea has been evolving in my mind as something to put in the arcade, but if that's going away maybe just a mode.
