the is really good, there's only one problem, the text is a quite hard for me to read, maybe make a option to make it like normal text for people who can't see clearly, and also the fire spreading mechanic could use some work as sometimes the torch would be right next to something but it would not catch fire and I would have to restart it again. Either way it is a good game
Agreed about the text. I've since learnt more about rendering text in Unity, so I'll have more font options in future.
On the torch not always setting things on fire - that's by design. A single torch isn't hot enough to ignite certain objects, like a tile-clad roof. The idea is for you to have to find more flammable objects to ignite first that allow the fire to spread to the more stubborn areas.
That said, some levels contain objects that look like they should catch light more easily than they do. I had to fudge the numbers to make the level more interesting to play - room for improvement there.
Still, glad you enjoyed it!
