It's a really cool concept and it's really well executed. It just spirals out of control too quickly and you feel like you're spending all your time putting out fire and getting nowhere...like life.
I think if you added some end goal that is well communicated to the character, it could increase the tension and fun. Maybe you're trying to protect something in the inside of the forest and the fire is encroaching from the outside? Just a thought. Anyway, cool stuff.
