Am I misunderstanding the tile puzzle? [SOLVED]

This is my first time dealing with a Tile Puzzle and I think I might have bugged it and nobody in Global Chat seems to have a solution so maybe someone here can help me.



My understanding is that the order I have to step on the tiles is LIGHTNING, COLD, FIRE, COLD.

However...



No dice.

It should be noted that I've found tiles that don't trigger the darts but don't obey any sort of order that I can understand and don't open the door, even if I make it across without triggering the darts.
The tiles that don't activate the darts don't activate at all either, they don't make a clicking sound or anything, though I'm not sure if they're supposed to??

Does anyone have a solution for me?

You said solved but for anybody else reading, you can't go diagonal. The third tile should have been screen right.
