This staircase was a PITA. I died at least ten times during its construction. And shaving the bottom of excess stone was arghhh.
looks pretty sweet (was going to comment re sperm but you beat me to it
.. maybe you can turning into a snake or a dragon or something)
Don't know if it'll help but my technique for inching over the edge is to do it sideways rather than straight on.. let's see if I can describe this and have it make sense.
-go towards the edge you are trying to see over, somewhere safe, say half a square away
-point yourself so you are parallel to the edge then angle slightly in the direction of the edge
-tap forward, now you should be a bit closer to the edge
-if you are now close to falling of the other side of the block point yourself parallel to the edge then angle slightly away from the edge
-tap backward (alternatively you could turn 180 and repeat the forward step)
-repeat the zig-zag process until you can see a bit over the edge and place your block
I must have placed 300+ blocks using this strategy and fallen maybe once.
Regarding the excess stone, two tips (assuming you know in the first place it's going to be excess):
-use dirt instead of stone it's easier to clean up
-remove it right away, usually you can find an angle so you don't have to come back at it from the bottom
