Odd , haven't encountered that before. Unfortunately I had two backgrounds, the censor and the black color from it, and I wanted to export with the back bg so it didn't look as buggy if it showed up but time pressure got me and I forgot :[
As far as the firelight power I tried to make it clear where the firelight was (3 tiles squared) and if I had more time I was going to add a particle effect on tiles with "firelight" when you have Wards. Also, pieces avoid it typically but will break this rule if it kills you on that move. This was not obvious enough which was an oversight :(
As far as the font I used PICO-8's regular size which is cramped but legible. I considered using the puny font instead but it's just much harder to read.
And finally, as far as an indication on where to move I had considered it as a feature or even a card but I ultimately decided that it makes the game too trivial.
Thanks for playing, and for the excellent feedback :>
