Lovely puzzle game with super original idea! I really enjoyed playing it a lot!!!
I'm in love with the graphics and the sound effects and music! It really felt like a very polished game. and loved the level design!
My only critique would be the controls. Personally (I really lack patience) I found that it was very tedious to move the mirrors and prisms one step at a time, pressing space for every square. Maybe press space once and then be able to move it as far and long as you want, before pressing space again, or I would have preferred to rotate them and to move them with the mouse, but the character is so sweet and cute, I'd hate to see her gone.
Plus at the last level, I think I found a solution that requires one less mirror, but maybe that is intentional:
