Collect blossoms and grow, without getting tangled in the existing jungle.
This entry follows both themes, Two Button Control, and Growing.
Use left and right to rotate the camera, and avoid growing into the blocks of leaves. Collect blossoms to score - each blossom you collect creates a branch, and speeds you up. Branches grow cocoons, collect mature cocoons and slow yourself down.
I'm personally quite happy with how the vine looks during an established game.
