It's so addicting, I kept playing it and playing it. I've seen a couple of snake / ouroboros themed games here, and this was definitely the most fun! There's only a few pieces of feedback I have: first, sometimes my inputs weren't registered correctly. I pressed up, and I didn't go up for example. Might be my keyboard though. Another thing is it would be great if there's one button you can press to reset when you die, for example R, that immediately restarts your game instead of having to click on main menu and then click on play. I also think the starting speed is too high. If you start slow and slowly gain more speed because of red blocks that makes the game more accessable. I think it's a bit hard for me even the first few levels.
Anyway I'd love to see a more elaborate version of this game!
