Thank you for the feedback! I heard the same thing from someone else, that they expected to be able to "control" the path the fire took. The problem here is a lack of explanation for the mechanic, that being that you select a tree stump to light, then the fire will take a path climbing along the branches and your goal is for that path to end at the tallest tree. In regard to the timer, I'd like to experiment with giving the player a lot of time to make a choice at the beginning, then shortening the timer as their score gets higher to increase difficulty, that could end up being more fair.
