SparkFire is a tap-rate hearth game where you must rapidly tap the screen to strike the flint and throw sparks into the fire, a higher tap rate makes the flame stronger, but more than 12 taps per second makes your hand shake so the sparks die and count as a fault, the flame must stay inside a target band that tightens every 10 seconds while natural decay also speeds up, dropping too low extinguishes it and rising too high burns through, three faults end the run, and the score is survive time times 10 plus average tap rate times 5 plus a stable-flame bonus.
This is a casual game.
