For an 'unfinished' game I think it's remarkably good! Played it to the end, once I figured out I wasn't the giant fire, but the tiny one. I was thinking there might be a way to make the cost of moving to a tile clearer, but then I realised I was quite enjoying the trial and error process of learning by experimentation.
I'd have appreciated being able to move the camera. Would have better shown off your 3D work, and would have also been useful when the ember is way off in the distance.
Anyway, thumbs up from me!
