I think there's a lot of potential here with an interesting concept and some nice visuals! My only criticism really is that the real-time obstacles don't interact well with the turn-based movement and fire spreading. I can always stop and take my time as the fire won't catch up. To fix this, I think the obstacles should be turn based too, and would allow more interesting puzzle design. (Alternatively, real-time fire spread would work too and make the game more intense --- so the fire spreads behind the player and ticks into neighbouring cells every second, for example.).
I was looking forward to playing more levels when I finished, which is a great sign. Nice work!
