Lots of Timing

Spoiler: Video Solution

Spoiler: Recovery Card 1 - sets up the first ball auto pilot

Spoiler: Recovery Card 2 - set up just before the 2nd ball auto pilot

Almost gave up on this despite seeing the gameplay due to my number of restarts. And the ball pushed at 1:21 did not roll the full distance twice which was frustrating. Decided to have one attempt at making the stack when i got that far and fortunately it worked. Earlier i was lucky when a move failed

Spoiler: Rescue move

after B got to push the higher of the two balls that B pushes, my block of R had failed but B is able to chase after R and overtake and make a block to get R back . For the stack formation i kept Z and R the minimum distance apart.

Yes lots of timing and you should provide a recovery card for this one. One mistake then it's game over. The first timing was okay as the ball paths are same(metal rounded blocks) but the zapper ball seems to always roll faster so Z has to be released later. Took me about 5 restarts to get that then onto the second timing which was a bit frustrating as it's a "wedge vs grass" situation. I still couldn't get it after 3 tries. Moved on to solve it in my brain and I could see the ending and the move for the stack but haven't figured where exactly to execute. Will try again tomorrow.

@ohmytian - I will provide a recovery card - I'll check for an appropriate spot

PS - Your recovery card is now available

Lots of timing, lots of FUN... as a big fan of this kind of timing levels I enjoyed a lot this one... only one difference: the second ball you pushed with L , I pushed with B leaving L stuck where he started... thanks for sharing @Meko Guy great job!

That was LOTS OF TIMING ( Pun intended )
Good design ✓
Good gameplay ✓
Very cool level

Thanks for the recovery card. I used the second one a lot and my overall gameplay was identical except mine was messier.
