I survive about 1ms if I don't change the speed... Level two should have more planets! And maybe something that repels the snake.

I just managed to travel through myself (so to speak) without dying... Not quite sure how I managed it, but there might be a small bug somewhere along the line!

It's a known bug (although I was pretty sure it was fixed). I presume you were heading towards the world? It's because the snake is built up of points, so many points that it looks like a curved line. Two points make up a line or segment of the Snake, so for collision detection I just check if two segments are overlapping. However I was scared this could become very slow when you end up with thousands and thousands of points in the Snake so I only compare the first few (I think the exact number is 5) points at the head of the Snake against all the rest of the points in the Snake's body. Personally I think of it as more of a quirk in the game rather then a bug (like how in the original Pac Man there is a position on the first level where you cannot be killed by ghosts). It's also quite dangerous to recreate because you can only do it reliably if your both close to the world and heading towards it (the gravity of the world makes you fast enough to do it). Typically the closer you are to the world the more likely you are to crash into something and die.

Ah I see :) Nah it's cool, wasn't trying to pick holes or anything just thought I'd point it out in case you weren't aware of it!

I love this game, the comments crack me up, and the snake is so.... sinuous! But I was really expecting to crash into different continents, not Australia every time I hit earth. :-)

@MathManiac: that's still not that high. At my personal site there is a version which includes a highscore board at: www.StudioFortress.com/space_snake
