Smarter than a fb Worm

[bplus]

Hi Bplus
I like very much your Snake AI demo!
Snake appears very smart in movement and catching food until its lenght stay under 30 blocks...
but I loose something, because some times it appears clearly a collision at the next step between head and body of snake, while in other situations it is very hard to see why does it return collision.

The reason for the crash is always in the title bar.  

When the head tries to do an 180, go in reverse, you don't see much difference in position. Just notice the fruit is on the opposite side of the snakes body as the head.
