I take this as platform precision.
As for my opinion, I don't like the fact that you are sent back to main menu after failing once. It makes replaying unpleasant cause it takes more time. I suggest making it like this after failing:
Press X = retry, level is restarted.
Press C = return to main menu.
Also the danger sign has same color as platforms giving impression that you could step on it, which you couldn't.
