Wow! That's great feedback! Really cool! Thanks for taking the effort.
I must admit, this tutorial was a struggle; it's quite hard to imagine any given individual to cater to... but with this kind of feedback I can really fix it.
I'm picking it all up on my backlog (README) as soon as possible.
I was thinking about a perch of attack pigeons before (in stead of the missiles)... Then the launcher-pads would be their perches, right? I have a lot of 3D modeling to learn.
