CatWalk: Claude Opus 5.5 One-Shots a Playable Game, Only Tweak Was Quieter SFX

Developer blitaststudio, seeing Opus 5.5 hyped as a game-dev powerhouse, tried it himself: from a vague description of a game called CatWalk, the model one-shot a playable game of a black cat leaping gaps, crates and boats along a moonlit canal — covering details he never asked for. His only revision request: quieter sound effects.
He likened the experience to a sharp dev saying "I mocked it up real quick," and noted that if a humble vibe coder gets this, real developers will ship far more.
