Experiment with changing initial circle on map drag

Thanks John. It's interesting alright!

I don't like how when you zoom out, the centre moves. Also when you move horizontally (on desktop and mobile) the circle gets clipped / cut off (I assume by the newly rendered map tiles). And it kinda glitches when you zoom in and out.

I imagine there could be ways to make it smoother, this is just an experiment of course. But what do you think of the idea now? I'm not sure. Even if it was smooth;

• If I send you a pre-defined location so we can play together and then you change the location, there's a confirmation dialog to warn you. Now this'll appear if they scroll or zoom. It makes sense but I don't know if I like it. I made this with older people in mind and I can imagine them accidentally scrolling or maybe zooming in to make sure the area is correct.
• You didn't do this but since we talked about it; maybe I'm wrong but I don't know would it work for controlling the radius. We probably need something better. To use the same example, someone just might want to zoom in.

Maaaybe if they've moved N distance from the original centre, we could draw another circle (styled differently) with a popup letting them know they can tap it to change location. But I don't want to confuse people either; if that's shown and they press "start", it won't use that location.

What's interesting is what you did is almost like introducing a cursor on mobile 🤯

(Happy to just chat it through offline if you want)
