Various/Other Go Up Steps Not Down Outside The Play Area

@Denis Nazin did a lot of interesting research about this and has some fun levels that use this fact. (Unfortunately I didn't remember where to find them).
Basically, outside of the 16x16 grid objects are "invisible" to B. If you tap on one, the tap is registered as a tap on the ground beneath it, and B will try to walk to that spot. You can use that effect with wedges to do some interesting things. The card below demonstrates it, but if you can find Denis's levels, they are way more interesting than this.

 

Thank you very much my friend, I will now give the link. All these levels are in the "out of level" album, so I will give a link to this album. It will display all levels.

There is another interesting level that I have not published "Football Out of". It is in another forum thread, here is the link:
