You can get the clues in any order and there is no actual ending to the game. I chose to start with Clue 05 because it is the only one where you are required to leave the access item for the last room in an earlier room. Since the challenge rooms get harder the longer you play, getting 05 done early mitigates the difficulty.

I got lucky on this run to only get the rope glitch twice and both times I could drop it back into the room I was currently in.
