Are stone blocks in layer 1 in connection with net in layer 2 perhaps walk-through? Is there no block in vanilla Map 16 that acts like what I intended to do? I'll be aware of this.
Actually, I never tried touching that wall while on the front side of the net. I just went back and tried it now, and yeah, you can climb on the front side of the wall just as easily as the back side. Thinking about it now, I have an idea as to how you can make it work as intended using pure vanilla resources...
You could place invisible solid block sprites (like the one used for the switch palace corner tile in the !-switch rooms in the original game) along the edges of the wall you're supposed to climb behind, so that you "bump" into the wall if you try to pass through it on the front, but the invisible solid blocks won't affect you if you're behind the net, letting you climb behind the wall just fine. (Of course, you have to be careful of the sprite limit if you use invisible block sprites for this purpose.)
