Massive Path

Might have to zoom QR on this one.

@Don G Rowe - The QR code worked for me as is. Your level required 3 restarts, the 1st: wrong turn, 2nd: B fell off??? and third time's a charm. Thanks

Not your best level IMHO... little bit obfuscated and repetitive... Thanks!

@chemi Thanks for the feedback. I was wondering what a big level without any sliders or motors might look like. So I started off and quickly realized that without those, the whole thing would end up a one-tap win unless I could figure out some other way to put barriers in strategic places and camouflage the false paths. Hence the stairs, which ended up with some good, and some not as good outcomes.

I like very much the concept, even if it resulted quite easy (almost completed at first try, but B trapped itself walking diagonally at one stair), and it was easy for a noob like me only because I mastered Springboard Stair recently (thanks @gmacpro) .
But I get that building something like this must be very hard/confusing.

Spoiler: Maybe

the fact you used only 2 staircases going up per floor (there are 3 in floor 0, but 2 still lead at the same spot) could have affected the difficulty.
And by taking the first correct staircase you could not be wrong, you can find only one staircase after that

@tebkanlo Thanks for taking some thought. One of the challenges I always find is how quickly you run out of space when making levels. This one compounded that with tap accessibility. I also try to lean towards the easier side on long levels, and save harder challenges for shorter ones.

At first sight, I found this puzzle too intimidating but I soon discovered that many potential roads had a dead end. By tracing the path back from the end, it became soon clear which path B has to take. Everything worked well. Excellent puzzle!

Like @GFJ, I started at the top and followed the path backwards to the beginning. My only issue was having to zoom in and out a good deal. The entirety of the level didn't fit well in landscape mode on my tablet but shrinking it to fit made the springboard stairs in the interior difficult so had to increase it again. Think that just goes with the size of the level and didn't really detract frk m the gameplay.
