In my previous several sessions I was far off and was stumped by this trash level.
Although this is named a trash level, this does remind me of some issues with preparing blocks that I am not proficient in.
In my previous sessions I couldn't get close before seeing this main idea. Then I saw the 128 today, took several tries to get the good sequence to get 126.
The ka-tet may actually enjoyed fighting through this one?
Not too difficult to me and I had a great session with this one.
(note: I tried this in level editor, so don't take reference of my solve time)
