I quite liked it, even if there was no clear end condition (was there?) With the way the fires went out after a certain amount of time, it was _very easy_ to get lost trying to find your way back to that one fire you forgot to light, some atmospheric music/sounds would have been really nice!
(nice work btw, as a first 3D thing)
It's more of an high scoring game rather than one with a clear ending. If you get it hot enough, the map'll lit up, which is a minor "You're doing well enough." reward I guess.
And yes, music or sounds would've been great, but I like making most of my assets myself and there were things higher on the list to take care of! Maybe once rating's over I'll roll out one more release with some polish, we'll see.
