You were right: below about half light the lines fell out of the circle, so a low flame was a sure loss. Fixed in the build that is up now: whenever no line is lit, one moves into the light (just above the flame when it is tiny), so you can always commit your way back. The decay and the bites are unchanged. Thanks for playing it that closely.

Checked the new build (20043045) with the same script as before: 3 runs, logged out, Space every 0.3 s on a 1366x768 window.
It works. On the old build my commits stopped dead once the flame fell under about 0.47 (stuck at 194 for the last 5 s while it burned down to nothing). Now they keep landing on every press below half, and the flame climbs back: 0.30 -> 0.61 in one run, 0.21 -> 0.35 in another.
Every run still ended the same way: two bites close together took it from about 0.3 to 0 within a second. That's the second thing I mentioned (a keyboard player still burns 0 bugs: 235-299 commits per run, 0 burned), not something the fix broke. The new flame % under the mug and the "kept" number at the top make it much easier to follow what's happening.
