How to display a different message and animation, randomly selected, on each game over, as well as on completion of each level completion?
There is only one place where I found "randomness" within BB: timeline of stages, isn't it? I may be wrong
I would try to create your levels as stages in one world played one by another and when completed followed by random scenes displaying different Game Over UI. I'm not sure would it work but give it a try.
And how do I create levels as stages? I just can't get around to getting a scene / world to successfully end.
