andycivil's video: Glimmer and Gloom Hard level solution actually easy

I worked out this embarrassingly easy way to do the so-called "Hard" level on Glimmer and Gloom and I'm going to share it with you. Start by clearing down to the bottom right. Scan across like you're reading a book and wherever there's a tile wrong, click down, and to the right of it. If you're really lucky it'll just clear like that one did, but more likely you will end up with a residue of seven tiles which you can't clear because there isn't a tile down and to the right of it. This residue is always symmetrical so we are just going to focus on the bottom row, and I'm going to call them A, B, C and D. You need to click the three top left tiles according to these simple rules: Click the first one if the tile A is wrong. Click the second one if the tile B is wrong. Click the third one if the tiles C and D are different. Then clear the board to the bottom right again, and there should be no residue.
