Nice implementation of this concept! music, artstyle, gameplay is all really coherent and feels like a well designed package. I had a few annoyances, like a 45 degree mirror that once reflects a beam 90 degrees, and another mirror at the same angle that reflects the beam 135 degrees, even though the beam hits them at the same angle (level 6). I am not sure if that is intended, or my calculations are off? 😁
