Up/Down = Select Ring
Left/Right = Rotate Selected Ring
Space + Left/Right = Rotate All Rings
Maneuver the rings to pick up incoming blobs in empty spots. Make the number of combos shown in the middle of the wheel before the counter reaches 0 to complete the level.
When a blob gets rejected, it will appear at the bottom of the screen and your health will decrease. Make combos to free a blob and clear the wheel. If your health reaches 0, it's game over!
