Got to level 8. A lot of survivors-like seem to try to innovate by adding more active controls, and I appreciate you not doing that. Even boiled down to the very basics here, the gameplay is pretty fun.
This reminds me of a very old game called "swear" which was basically snake, but on various non-euclidean geometry. I think it was clearly better than normal snake. But I'm not sure if "survivors on a sphere" is a breakthrough.
Still, it works. I enjoyed getting forced over to the dark side and having to claw my way back into being able to see again (sort of).
