I'm a huge fan of snake games and ever since I first played the QBasic version of it called Nibbles [1] have wanted to roll my own.

From friend's play testing - I can say that this is probably the most difficult version of snake that exists until I come out with one where you control a third snake with voice commands. Most players can't make it past level 3.

This one can be played using WASD with the left hand and arrow keys with the right hand - but its way more fun using an arcade controller with two joysticks.
