Your entire freaking country is on FIRE! Everyone's relying on you, the only fire fighter to save their burning homes! They're freaking out, man. Spray water from your trusty hose using your LEFT MOUSE CLICK. Determine how much power you want when you spray, and choose your angle as well all by point your mouse towards the direction you think is good enough to reach the houses. The amount of water you have is limited so use them wisely! Sometimes you'll need to activate switches by pushing boxes onto them, yup some boxes can actually be moved! Good luck!
