This looks absolutely stunning!! and plays really smoothly! good job , it's extremely hard too. aiming for floor four!!! Am I bad?
So that there is no rigid algorithm to learn, the elevators change their speed depending on where you are and how long you stay in roughly the same place. Of course this makes the game quite difficult, especially the last 2 levels, but there isn't one that I haven't personally completed, so it's possible. But that's why, unlike the original game, I added the ability to continue and restart levels.
