## TODO

### Make sure there is a way out

When using A* and an apple spawn in an area encased by the snake, the snake
will happily go for the apple, even if it means there is no way out after.

We should make sure it never goes for the apple, if it means it can not get out after.  
Maybe we could simply test if there is a way from the apple to the end of the snake, and do some idle looping around the edge until there is?
