No idea how to play and had a hard time figuring things out. Maybe provide more indirect indicators for progress? eg. water visuals to show that the pump is working or blocked up, a progress bar showing the fire is being put out, or sounds of water rushing whenever you manage to connect a new pipe. Lack of visual indicators of the pipes means you could take advantage of other indicators.

I think this could be something if you had some kind of indication for the progress you´ve made.  For example a sound with corresponds to the number of pipes the water went through. So if it goes to three pipes (whether or not it is correct) it makes *bip* *bip* *bip*.

No matter what you think please leave some feedback, so i can improve this after the jam is over to a better more entertaining game.
