Gothic Chapel

This is as far as I can get. Any clues how to get P to where B is?

Hi @Chris Hester!
Yes

Spoiler

Don't knock the blocks out until Blue reaches the corner stone block. Best way to do this is get on the stairs two spots away from the ball. Then when he reaches just before the first metal block you set the ball rolling and he'll be stuck on the right side of the falling blocks.

For anyone who's interested I've added this

@IceBlade gotcha! Now I've pushed the ball on the roof but nothing has happened...

@Chris Hester
Ok, so

Spoiler

once the ball has fallen into the floor a secret panel opens up in the cross on the floor. But don't do anything with it yet. Get back down off the roof first. Then get B into position moving back and forward near the win. Now look in the floor at the cross and down inside there is a draggable. Move it left and something will rise up on the roof. Then after it stops move the same draggable right and the cross will rise fully from the roof. At the same time a ball will drop at the back, allowing B to cross onto the win.

Here's my rating:

1. I like the design.
2. I think to compare it to Mekob123's lvl.
3. Now, I rate it 5 stars!

I do complete it in the nick of time.

steps: 1 knock the block until the moment P (or l) gets to the corner stone. and so on...

Impressive raising of the cross. Liked that it wasn’t fully automatic finish.

Thank you, very interesting level. Interesting design, Beautiful transformation - very effective. The timing at the beginning of the level was not easy, I had to restart several times.
When I threw the top ball - I thought that something did not work ... But, I realized that it was intended that way. Cunning mechanism. But, when I understood the principle of the mechanism - I was able to pass the level without the top ball:

you can grab the main control slider through the walls and then you can go without the top ball

Thanks, I liked it.

@IAmPogi great news. Glad you liked it and won. Not sure what the codes are for though.

@ridgerunner thanks friend. I'm so happy you liked it. Yes, of didn't want it to be obvious to make it go up in one go.

@Denis Nazin thanks Denis. I'm so glad you liked it. I did try

Spoiler

preventing accidental grabs but I couldn't get it so I thought it was safe, but nothing is safe with talented people like you

I was fascinated with the special hidden door design and worked hard on making the cross rise like a surprise.

@IceBlade I think you meant L as B can't reach the win block due to the sunken step. Took me a couple of tries but I did it! Thanks for the help!

@IceBlade I just tried again and @Denis Nazin is right! I didn't need the ball on the roof! But then my timing was out and when I pushed the first ball, L fell down into the hole!

@Chris Hester oh dear this has descended into chaos
