Very creative interpretation of the theme! I enjoyed your game a lot! For a bigger game, maybe light shapes can come in more variety plus you could add mirrors to make really complicated patterns. Also, at moments when the solution didn't get accepted I ended up just making tiny movements looking only at the percentage gauge to maximize it rather than at the shape. While this gauge is a good way of making sure the player isn't stuck, it ruins the atmosphere a bit IMO. Maybe you can hint the correct position in a more subtle way - like adjusting the color of the orbs or something.
Nonetheless, great contribution!
