Played the itch build headless at six sizes (375x667, 390x844, both landscapes, 640x360, 1280x720) plus a bot that walks each cavern. Clean: 0 console errors anywhere, the pad sits well in portrait and moves to the side in landscape, and it pauses on blur/tab-away. The bot cleared all five caverns in about 2:10 of play. Light-as-clock plus a flame that points at the exit is a tidy torch idea. Three notes, all about the draft:
1. With no draft, the flame still looks like it is pointing somewhere. When you are out of draft range, computeLean aims the lean at straight up plus slow noise (up to about 60 degrees either way), and drawFlame tilts the flame along it. lean.m (draft strength) is computed every frame but nothing reads it, so 'no draft, wandering' and 'strong draft' only differ by how steady the flame is. That matters most late: draft range is 70 tiles in Gloom Hollow but 32 in Ember Stair, so on that cavern the flame gives no real direction for about 80% of the shortest route (and 89% of the open floor). That drifting 'up' lean is easy to read as a draft. Scaling the tilt by lean.m (flame stands straight when there's no air) would make the draft an honest signal.
2. In Drowned Galleries the draft walks you through the pools. L.de is a plain BFS that treats water like floor, so the shortest route the flame follows crosses 21 water tiles. A route that counts water at its real cost (1/0.55 per tile) is 31.4 s against 34.2 s, about 7 oil saved. That runs against the level's own tip ('go around them'). A weighted search (Dijkstra, water cost about 1.8) for de would fix it.
3. Small: at 640x360 the title card overflows by about 37 px, so the 'Enter or Space to begin' line is cut off unless you scroll the card.
