Thanks for playing, and for the specific notes. You're right about the oil lines. I looked at my own screenshots: unlit trails are dark brown on near-black stone, so you can't easily tell where two trails meet. Fire really does follow every touching oil cell, so the drawing is accurate, just too dim. The post-jam update will brighten the trails and mark junctions. The early boards are also getting harder: a few levels have kegs that never affect your choice, and those are being replaced. I'm holding all changes until voting closes.
