When You Die, You Go Back to the Beginning.

I agree, but that isn't a challenge. It's just an incentive to not fail. A challenge would be something like a difficult boss, puzzle or the like. It also artificially increases the length of a game by making you repeat the same stuff over and over again. But failing is going to happen regardless, for first time experiences and human error. Such punishment is way too extreme IMO. Send them back to the start of the level or a checkpoint. But not back at the beginning of the damn game.
