Herder is a switch game (one-button game) that you can play instantly in your web browser. Hold the left mouse button to change the orientation of the snake's rotation, and encircle the bubbles using the snake to make them disappear. In order to eliminate the floating bubbles, which is the objective of the game, you need to have the correct orientation and the snake's color should match the bubble's color - this will be better understood once the game is played, and I think it can be easily figured out :). Try to herd multiple bubbles at the same time for bigger points!
