Very nice game! A neat idea, really fits the focus/limitation. The concept of saving water is really unique and the art is very cute! Of course, there is a firefighter and flames and stuff, so it fits the theme too. Really nice animations. I was a bit frustrating to die at the end of the level, and then do it again. Maybe you should make a health system, or make the fire put out much quicker. The movement is a bit sloppy, so I slid right into fire sometimes, but that's okay since it's the your choice. I'll say it again, I really like the art, animations and graphics! The 2D lightning really fits the style!
Good job overall. :D
