I like this very much. BUT: What I cannot save I do not remember (quoth the Old Guy). Any way to save these images as SVG. (Screen grabs are less satisfactory.)

Awesome! I haven't had this much fun since r/Place.

The ultimate territorial acquisition strategy seems to be as follows:

- Pick a desired colour

- Choose a place to found your empire, ideally somewhere with a lot of large rectangles and a colour that takes few clicks to turn to yours

- Left click tiles to capture them for your colour

- Right click those same tiles many times to subdivide them into areas much smaller. What took you 1 click to capture will now take anyone else hundreds!

Misread this as MMOndain [0] and thought it was going to have to do with the Ultima games

Love the idea, silly as it is! What came before, the app idea or the pun?

Pun

Does this use the DeStijl manifesto. There were actual rules about how to use color and lines.

My edits disappear either right away, or I can recolor for 20 seconds and then it gets reloaded with the previous colors.

I think I'm having stability issues with lots of users, will try to figure it out, sorry

OMG I thought I was fighting with someone really fast.

I thought so too! Maybe it was true

No need to apologize, just wanted to let you know there is an issue.

It looks like you need to batch your updates and not tie them directly to UI actions, imo!

Cool project!

I can't seem to pan, it would be nice if the zooming would zoom in to the mouse location. (I did manage to write HI near the left edge though.)

Removing lines doesn't seem to work, it flashes out but then stays in.

Have to click on black lines. They can be moved too.

I did, it flash out, then it comes back in.

Doesn’t seem to work, just unclicks whatever I click.

Same. I thought I was in a battle of wills, and I guess I was, just not the way I thought.
