Let's talk about why you think that:
In Buckshot Roulette, the players take turns firing either at themselves or each other, with items that modulate the gameplay, and a (sometimes variable) expanding health pool, with limited revives from an onsite doctor.
Compare with this game which has an added tolerance mechanic, almost ensuring you'll take at least one hit per play-through and adding effects to what mechanically are equivalent to BR's blanks. There are no items (that I experienced) which allow you to heal OR increase damage, nor can you steal an item from your opponent; you can merely copy it.
Push your luck games with a lethal twist are nothing new, and variance caused by picking along with statistics rather than a randomized load order means a more controlled form of push-your-luck than BR, even if this game may be inspired by it.
