Online Sandbox Canvas

So, I am learning the basics of multiplayer games, and probably one of the simplest game to make is this: an online sandbox canvas to draw pixel-art, when any user can connect into and draw something just for fun. (⁠ ⁠╹⁠▽⁠╹⁠ ⁠)

The ability to track other's player mouse and their usernames, or even the color they have selected is what makes this feel "alive", like "I'm not drawing alone". Even something as simple as having another pixel moving around you and drawing, or just following you makes you feel like this is something different. 

I did a couple testings with some of my friends, and it was so funny to annoy their drawings, or just standing next to them while drawing. I was considering the idea to even add a chat to interact with other players a little deeper, however, I was afraid about... you know, what having a chat means. Is not about the language, but the content itself.

The game right now seems almost perfect to me. I would like to make the canvas bigger, because right now is just 60x60 in size. And maybe in the future add a couple of functions to zoom in/out, or something like that. But first, I'll let this game go as a boat in the ocean, and check what happens next.
