Nice presentation. Different ways to play. When you open a trick at the beginning, it can be used in between the game as well. Next time ensure it usable where you design it to be used. Make a cheatproof game. Spoiler I won both ways. By going on Metal Stairs and without going as well.
For bots, the shift of the metal ladder is not necessary. Therefore, as far as I understand, a metal ladder shift is only needed to let the ball through! And then return to the place. Interesting level, thanks.
