Sorry it's unreasonably strict for you, different people have different expectations for sure. This game has a 0.07-second window on both sides. We chose the stricter side of things for this game, since the difficulty in other areas (multiple buttons, dense inputs per second) are nerfed by the core mechanic. We'd recommend games like Crypt of the Necrodancer if you enjoy more forgiving timing. Thanks for the comment, it's appreciated!
