Nice art, good concept. It's pretty fun! I think more visual feedback and sound effects could be good, also the wait between some turns is a bit slow. I wasn't able to place water despite having the energy to do so. Nice job!
I think you might have to fix that, it makes it a bit difficult to get rid of fire at times. Maybe just have water extinguish the first fire in the row.
I went for that approach because it made you think a little more about what you burn, since if all you had to do was use water on the row it would be too easy.
(But let’s be honest like this is a game Jam this kind of stuff was thought for not very long :L)
