There is a fatal crash bug in "Snakey" which sometimes occurs when you eat an apple. It may have to do with the next apple somehow spawning inside the snake, per the output of the RNG.

Hi,
I just uploaded a new version that should fix this, the problem was not the food entering the body of the snake, but my checking for a new position for the food that prevented the new food position to be in the snake's body. The condition checking was wrong and it could lead the game into an endless loop if you for example eat the current food while having traversed the whole screen vertically with the rest of your snake's body. It could also be reproduced in some other ways but this was the easiest way to reproduce it.
Thanks again for reporting this.
