@cimarronline @BLR thanks for the reply. now I'm a bit confused, your (BLR) level is dated from 12.05.2022... So how can I finish it, if ToA is not working anymore...?
@RonaldN That's not really ToA in this level. I think it was a misunderstanding. A different trick is needed. It is discussed above in the comments.
@RonaldN it's not a ToA. It's actually a cancel half block trick - i don't know about that trick before. @cimarronline was true, it was misunderstanding cause i don't know about "cancel half block" trick before.
Puuh... Not so easy to set B between the blocks. But finally I got it... Thanks to @BLR and @cimarronline for your support...
