Final Match

Why did you repost the level?

Spoiler

I'd like it more if you don't hide the draggable and I didn't understand the reason of zaps.
Anyway good level,but the original will be always my favourite.

@LooKing? I tried the "shortcut" you mentioned about crossing the river (I still have your previous version ) but B only managed to cross it 2 out of 50 times(I tried different combinations of starting and ending positions), and even in those two successful attempts B overshot and fell outside the level. So no worries, I'm sure it's way easier to find out the hidden solution than to retry it over and over

@LooKing? 6 would be impossible I did cross the 4, though it only worked very occasionally. I wish there could be an option to speed up the rotation just to play safe

Ohh, while we're at it, you made me curious whether B could still cross the river......And I'm very surprised to confirm that he can, even in this version with an 8-unit mill! Though it seems to require a very specific path and tapping technique when instructing B when and how to move.

Spoiler

1. Firstly move B to the opposite corner -- not the corner grid, but one grid closer to the midpoint. This forms an exactly Z-shaped pathway from his spot to the leftmost zapper (you would have to tell B to stop by the zapper).
2. As soon as B arrives at the beginning of the Z-shaped pathway, immediately tap the grass next to the leftmost zapper. If you're lucky (yes -- it took me countless retries only to succeed once!) you'll see B performing a sideway somersault over the mill, and keep moving towards the Win. The somersault is the key here because if he fails to perform the stunt, he'll fall into the water. Note that the somersault doesn't guarantee B's success, but if you did see him doing it, you're very close to the Win.

So I don't think this shortcut would be completely fixable by lengthening the mill's axis, since the technique I used above may potentially be reused with an even longer pathway starting from the house's side. The safest fix might be to embed a ghost block zapper inside the mill (note that a ghost block's motor would not rotate when its parent motor is rotating -- the spin cancels out ).

And......I took a picture of it

Spoiler

As you can see, the mill hasn't been jammed yet B crossed the river It probably worked 10 times in 200 attempts, most of the time B misses the target (yes -- he can land exactly on the Win) and overshoots even when he managed to get through the mill. The key is to get B to perform two somersaults to survive two flaps of the mill, so that he lands directly on the other side.

@chemi I know right It was so hidden!
