It's also, unfortunately, not a real game, but rather a concept created by YouTube video effects specialists Pipoca. The experience communicated in the concept video is wonderfully tense. The explosions lick at your heels as you jump out of the way, bits of bricks flying in all directions. Your opponent remains hidden until you're too close for comfort, otherwise only vaguely indicated by intermittant eruptions.
I would play this until my fingers fell off. Then I'd use my teeth. After that, I'd use yours.
