Rollin In D Deep

The first part is quite tricky but if you're familiar with how the ball on wedge works, you're good to go. B will be able to descend one block lower than its original position.
The rest have no tricks.

Spoiler: What should I do after I bump the ball?

Stand on the ball.
Let the motor rotate.
B will go up and down.
Once B is on its lowest point, press the neighboring stone blocks or the motor.
B will then fall to the ground.

Afterwards, players who dislike tricks may play with ease. Players who love tricks may opt to perform autopilot to shorten their path which is still fine.

@P_simorf - Too bad the level has that constant rattling? I couldn't wait to get to the last one and release it but the high ball missed and rolled away .

Nice level - the rattle can be eliminated by releasing the auto rotors and stop them when needed. I liked that feature as so many authors give you one chance and if you release by mistake doing a swipe to rotate the screen then you start over. I did push the mechanism the wrong way the first time. All worked out the 2nd time.

@Meko Guy , thanks for P, C, and R!

The ball is also rattling constantly on my phone. I haven't experienced the ball rolling on its own even after landing and rattling on the wedge. Nonetheless, I'm glad that you enjoyed my level! I'll also look back to your levels during my free time.

Great gameplay and I like the use of the middle rotor and slider. Thanks for sharing @P_simorf

Absolutely fun!

Noise can be controlled.
I spent 2 minutes to understand how to get out from the initial place without zapping.
Later I got it when I saw the Stair on other side.

Ball landing on Hollow Slider was perfect.

Ride on Ball was perfect too.
Glad to see that Ball didn't lose before B reaches there.

By the way, it has one trick involved...
Slider Freeze!

Amazing level!! So,so fun!! Thanks for sharing @P_simorf

Excellent level !!! Great logic of sequence and movement! I really liked it!!! This is a cool level! Thank you for this puzzle !!

This level is very good.

A few tricky bits, but a lot of fun. Just please allow me to be the first one to say:

But this sad song can have a happy ending, can't it?

My next challenge is to figure out the optimal order for doing everything, rather than running around, saying "oops", and then running back to where I was. For example, after falling,

B has two different ways it can go.

OK, this is crazy, but I created a video for this level with ITS OWN SOUNDTRACK. I created the soundtrack in MuseScore & then adjusted the video length in Olive, the video editor I use. (So you might notice that the gameplay looks a little sped-up.)

Spoiler: Video Solution with SOUNDTRACK

I had a crazy idea to start with the song that the level title reminds me of, but since it is a mad / sad song, I made a number of modifications to make my instrumental version happy & light-hearted for B instead. If you know the original song, you might find this funny as I did. If, however, you don't like the soundtrack, then I offer you the mute button and my apologies.

Took a while to figure out how to get B down as I didn't read the hints. This was an excellent level full of figuring out which ball or route to do next. Very much enjoyed the intuitiveness of this map and thanks for sharing
