Open Snake

It is compatible with both keyboard (WASD) and touchscreen devices.

The purpose of Open Snake is to be modded! Since it's so bare bones, you can experiment with ideas to make the game of Snake just a bit more fun. Here's some ideas to get you started:

The game gets increasingly faster as the snake eats more food
Food will increase your snake's length exponentially instead of linearly
Additional food types, such as a super food that gives your snake three more tail pieces
Food that keeps moving every five seconds if the player doesn't reach it quickly enough
