Re-using your deaths to complete a level

While working on the game, we added corpses to mark the places where the player died (you keep respawning in the same level until you complete it). Then we told ourselves that it would be nice to interract with theses bodies.  Like jumping on floating bodies to get pass an acid lake. It means that you need to die a certain number of times and it will impact your score but you get rid of the obstacle.

I don't want to make it mandatory to complete a level, but I think it is nice to have alternative ways to achieving your goal. What do you think about this "feature" ?
