Just wondered if anyone can help me with where to use the mirror to reflect the sun. From what I've read on the thread, it should be before going up into the tower but I just can't find the place to use it before getting stuck with no options left to try up in the tower by the red door/red ball. I've traded all the coins in and am pretty sure from what others on here have said that I've got all the right objects by this stage. Any help about how to progress up the tower lift shaft/mirror would be much appreciated! Just cannot think where there is any sun!
