I've played slither quite a bit, and I find it very stressful, it's hard to survive and very frustrating when you die, but I do think it's a brilliant little game.

If you get the mod so you can zoom out it gets a LOT easier! I play on the Pacific Servers a lot, if you see me on there I am LARGE MARGE. That's funny you find it stressful whereas I find it relaxing.
