i think the game is unbalanced as it takes lots of effort to extinguish a single fire and there're plenty of them left
i felt that i couln't do much(
shift didn't help much either :(
maybe you should've gone even far overboard for player to make it clear that this is a big exaggeration) like when he tries to poor water on fire it makes it grow as if these were plants) the triky part is to show player clear action/cause move)
because when you've accomplished extinguishing 3 fire from all of them there's a slight hope that it's could be possible if you try harder and if there're more pressure in the hose) but if you keep playing you understand that is unattainable and it makes you sad and hopeless so no fun emotion about you game)
on the other hand if player clearly sees that when he uses a hose the fire grows even more - he'll quickly understand that this is all a joke) and kinda fun idea)
