I liked the dialogue between the characters, the setup for the story in the future, and the core mechanic of the game seems to be there with managing the guys, also I liked the music (though it did stop eventually and didn't loop). Also the character design was cute!
I was very confused when I got into the level itself as to what exactly I had to do, and whether what I was doing was working. I assume I was meant to press E to motivate the firefighters to put out the fires, but I wasn't sure whether that was doing anything, if you do go ahead and develop it more (which you should!) I'd say make that clearer as to what to do in the first place, a tutorial of sorts for the main gameplay.
Overall, a good submission, was fun to play about with.
