Read this seven days late, and I checked every point against the current build instead of arguing.
1. Holding the button: you were right. Pressing is running now, and an unshielded gust takes 0.22 of the bar on the first road. My harness policies: press and never lift dies 65% along road one; press the right side and then brace down again banks 0 of 6. What stays true from your note is the leg length, about 5.2s at full run, so one unshielded gust still will not end a run.
2. Leg start: fixed, with a correction I had to make to my own sentence. Road one starts on the design flame, and every later road starts with what you handed over plus a flat 0.32, floored at 0.34. I wrote "floored at a coal" in the first version of this reply and it is wrong: 0.34 grades as a fist of fire. So handing over a spark still restarts the next road with a fist of fire. That is the additive refund you would expect, and it is still in the build.
3. Last card: it says "tap to carry it again" now.
4. Straw: I flipped the wind side after this comment. The side you press is now the side the straw blows toward, because several readers reached for the streaks before the flame.
All four were real. Thanks for reading the code and not stopping at the score.
