You don't even need all that complicated crap, you can just choose "go back to the map" in pause menu it will not save anything that happened in the level, including deaths.
I'm also pretty sure it's a deliberate decision by the devs to have this in. It's listed as Tip in the manual on their website.

Donc en gros le retour à la map ne comptabilise pas les morts. De plus selon cette personne, c'est une décision prisent par les dev', il n'y a donc pas de risque d'avir une maj changeant ça.

Return to Map
If you no longer want to play a level, you can choose “RETURN TO MAP” from the Pause Menu. You will lose everything you earned in the level. It’s like you never played it at all.
