Nice to know that the platforms were made with ascii! the "hapax" submission also have some nice elements drawn with letters that almost disappear on the big picture. They found a way to show this, making the level build itself at the beginning, but your way is also valid!
On the PC at the beginning, I'm not the organizer to enforce rules, so I don't know how they will deal with it. Maybe they agree with you that it is only illustrative and doesn't impact the gameplay :)
