Good idea, I hope children will come and join.
I was all mad at how it is in my town, long before 2020. No place for teenagers to meet in public space. Nowhere you see signs or open rooms for young people under 18. Either you are a member of a club or you can "corner". Which is fine for me, what else shall the teens do if not standing around and gather? They cannot go to clubs or pubs, too young for that but too old for things where adults are present and watch over them. Outdoor sporting places like football fields and half pipes are there, but rare. In winter, it gets worse. Nowhere to be in a big city. People complain about the young gathering. They are "too noisy or disturbing" and all that jazz.

They have built a huge hall here in the city where you can re-enact what you see on youtube when young people "jump buildings". Street kids often provide the inspiration for things that are later professionalised and put "under safety". And, of course, earn money with it. I am ambivalent about this.

So I really like what you plan to offer. I hope it will work out.
