Multiplayer online snake for many players. Question from noob

Seeking to go in the right direction. I have little experience in programming.

I wonder what is the simplest solution to create:

1) 2D multiplayer game with many / many players on the map at a time.
2) Zelda as graphic, not complexity. 🙂
3) Easily adapt if it satisfies me.

Can be mobile or based on the explorer.
If there is no easy solution, please let me know as well. 🙂
Is Pygame good?
The unit seems a bit too much.
