Here is some videos:
White section: Youtu.be
Red section: Youtube.com
I planned to upload some video from yellow section too, but something is very broken there :) I don't know what yet, but i hope i can fix it... Comment please.
Finally, i repair that ball... Here: Youtu.beIt's the Ball of Doom test. Ball of Doom - is the most important part of yellow section.
The Ball of Doom is moving parallel to the wall, in that direction, opposite to place the energy ball hit it. And it stops, when rich the wall, or player use it with "E".
