Keldon Line is a game focused on timing and attention. On a compact 3×3 grid, active nodes light up as energy pulses. Each pulse stays visible for a short moment, and accurate taps add points while keeping your streak going. If you miss a pulse, the streak resets and the score drops slightly, so steady rhythm matters.
The session includes two stages. The first stage keeps a calm pace with one active pulse at a time, helping you get used to the grid and timing window. The second stage can show two pulses at once, with a shorter reaction window and a faster tempo. The goal is to reach the target number of accurate hits before the timer ends. After the second stage, the best total result is saved on the device.
Keldon Line uses simple visuals and clear feedback, making each round easy to understand and repeat.
