Here’s a demoscene prod from 2013 that executes a similar idea in 4 kilobytes https://m.pouet.net/prod.php?which=61035

Fun idea. I think there's more potential in games played on real maps.

Fun, found myself going over the poles more than I expected.

I had fun, this is a nice idea. Would be great to expand this with a custom link that contains a list of places, with appropriate zooming, for school kids and teachers.

A missed opportunity naming this SnekTrek.

Bug report: the snake becomes shorter near the poles.

Awesome game! Great concept.

I love how this makes a metaphor for global capitalism.

Roam around the planet gobbling up resources and growing larger, until you ironically screw yourself.
