Gunma's Ambition -You and me are Gunma-

Unfortunately Gunma's Ambition's joke only sustains it through the one play-through. There's no real reason to aim for a better completion time, and the gameplay is far too shallow to sustain the concept beyond the joke. It's a great joke, don't get me wrong, but given how specific it is to the Japanese culture, and given how little the game has going for it beyond that, I can't think of a more esoteric experience that I've had on the Nintendo Switch to date.
