Fun little game! I enjoyed the gameplay loop of going around and watering / putting out fires which was fairly easy to figure out how it works. The art and music were very nice and helped bring out a cute chill aesthetic to the game!
However I do think that dealing with the fire spreading enemies was a chore to do as they appear without warning and end up causing too much damage before I can react. Perhaps adding some sort of warning indicator or icon to find where it is easier could help with that? I also do think that figuring out what to water was difficult as the patches of plants all look very similar to each other. A couple of times I just randomly went around and watered anywhere I can.
To finalize my thoughts, I think this was a pretty great game! With just a bit more polish this could be a enjoyable small release.
