This is delightful. The way you weave back and forth feels a lot like the action of rabbit and steel. This could definitely be turned into a full game.
The addition of a projectiles that need to be destroyed by a clockwise/counter clockwise sword could add some really crunchy challenge for harder levels.
If you're looking for last minute improvements, some way of communicating your progress per screen could give the player a stronger sense of how far through the game they've progressed.
Nice work!
