The music for the fire is excellent! The strategy that I found worked was settings multiple fires at once, some near the fire station and some in the forest. While the firetrucks deal with the local fires, the distant fires in the forest have more of a chance to spread. Even then, it seems like a delicate balance to not use too much energy.

Thank you man :) Normally I mute the music while developing because it gets repetitive to listen to it through the whole dev cycle,
but this time I just let it play and loved it so much :D
Also I think the tactic you described is the best one too. I posted a cheese strat image a bit further down in another comment if you want to check it out.
