I uploaded this, and then replaced it! It's had a graphical overhaul (i.e. it's got three UDGs).
I'm actually really pleased with the graphical health bar in the game - and it might be a shade faster than was.
Last minute update to this - bugfixed a scenario where the random placement of food meant that if it landed on the 'head' of the snake, it'd be not eaten. I think I've bugfixed it anyway!
