Sorry that I don't speak Spanish...
The graphics look amazing!!!
At first, I don't know what to do since there is no in-game tutorial on how to increase the flame meter. But after some goofing around (with audio cues) I learned that the mushrooms and falling leaves can restore flame and the enemies cannot die.
I like how the difficulty of the game increases diegetically, as the forest fire consumes the mushrooms before the flame can get to them. It fits the story well.
The only suggestion is to make the falling leaves more visible.
