X-thing

I was stuck on the ball

Spoiler

Getting back to it after going down so I needed the video as I didn't see the move. Maybe the water had an impact? Probably not!! Due to the close quarters and the wedges (in your design) it took a lot of tries to make the AP happen. I think R has a headache as it took 13 to 14 bumps and I play well over 20 times. Tried the springboard stairs to get past R and it wouldn't work? so needed the video again. After getting R out of the way, I had already figured out the finish or I thought I did. I will check the rest of the video.

Very glad that is over!

@gmacpro Yes I prevented SS with stairs under those stairs. Thanks for the feedback!

Maybe just the way my brain is wired, but had to watch film as this was counter-intuitive in the extreme.

Nice surprising last step (use of X). Very compact bottom part with some nice easy autopilots.

The last move was very interesting. Of course, I got some help from the video guide.
thank's

Got everything bar the last move, and even tried that move but didnt raise B high enough as i didnt see the gameplay and thought i might squeeze B through. Liked the ap move to get past the step. I was pushing the ball against the draggable, which not surprisingly, had only a 50% success rate.

Wow! Tricky but really, really original level. Loved that last effect. Thanks!

Wow!! Great tricky/logic with a very cool last step!! I love the design!! Thanks for sharing and excellent job @Block builder

Very clever little puzzle. Excellent finish! Much fun was had.
