What HN community is saying

Players broadly found the game engaging and addictive despite initial confusion about mechanics. Common feedback: the instruction "click the line" should be more prominent, as low contrast made the goal unclear. Users reported accuracy ranging from 0% to 2-4% average, with many praising simplicity. Requested features include timed modes, training modes with repetition, diagonal lines, and persistent score tracking. One commenter noted users can achieve 0.00% consistently through geometric calculation rather than eyeballing.
