I like the spherical design of the world, and also after I got it, I realised it was snake but on a globe, which is quite an interesting twist.
Some feedback:
I think the turning could be a little sharper. Perhaps it was kept that way to increase difficulty, but it also limited control and navigation quite a bit, especially when some areas are quite dense.
I don't know what are the random chopping sounds that occasionally play in the background at random intervals.
The trash tail wasn't obvious the first time, so I actually went to try to collect my own trash tail, thinking it was from a powerup, and ended up killing myself.
On the ideas side, I think the game could be more rewarding if at the end before dying, you see how far your trash tail is. I would have loved to see mine circling the globe just before dying, especially since the camera is quite zoomed in and you don't see your trash unless you circle back.
Overall, I dig the concept and the character :)
