Josiah observed carefully and then discovered the subtlety of it all.
One of the cannons, also covered in green, fired clouds outlined in green.
From a normal perspective of time passing, a white cloud and a green cloud drifted from right to left at the same time, with a significant gap between them.
But if time were to be reversed...
The green cloud would still move unaffected from right to left.
But the white cloud would start to be controlled by the reverse flow of time, beginning to move backward from left to right.
In this way, the clouds offset each other, filling the large gap in the middle.
Allowing the player to pass through smoothly.
This scene also brought surprise and astonishment in the chatroom! The screen was filled with exclamations.
Later, during Josiah's experience in the whole world 3, he found this game to be ingeniously designed!
