Played the 0.3.0-torch build on desktop with the space bar, best 18. The loop sells itself without a word of text: the spark comes round, the lit arc is the answer, and the window shrinking as the score climbs keeps the pressure honest.
One thing I kept fighting: the flame glow spills past the arc, so at speed the exact ends of the catch zone are the hardest part to read. A thin tick at each end would let me time the late catches instead of guessing them.
Also the three drops do not explain themselves until you lose one. Dimming the first drop with a small shake on the first MISS would make the stakes land right away. No console errors on my run.
To be straight about method, same as Smokey: the catches came from a small script of mine that reads the pixels (white spark, lit arc) and presses space, so these are notes on how the game behaves, not on how it feels in the hand.
