You play a firefighter, riding on your fire engine. Move forward and back, and up and down your ladder to reach various windows. Rescue people from the burning buildings, and put out the fires!
Whatever you do, don't think about spraying your hose on unsuspecting pedestrians, cyclists, or people enjoying privacy behind random windows. That won't go well for you.
I'm aiming to get this on Xbox Live Indie Games, Windows Phone, and Windows 8.
I'm aiming to give weekly (or so) updates on my twitter feed.
