This is not the most ambitious game. It's a simple idea, that does exactly what you said it does, avoiding any over-scoping or unnecessary features (Although I don't know what your scope was when you started). And while I don't think it excels in any areas, it doesn't have any areas that it is particularly lacking in.
First I want to talk about the art. It's not the most impressive pixel art I have ever seen, in fact without the text description on the itch page I would struggle to tell what some things are. That being said all the art in your game is cohesive and matches each other (which is much more important than the actual quality of the art). In addition I think the title screen for your game is clean and leaves a decent first impression (although the lack of transition into your first level takes away from that cleanness a bit). Also, the default unity bars used in a few places look very out of place and take a lot away. Just setting the visual on the bars to "none" and letting it be a solid rectangle would be better.
Next I want to go over the audio. I think the music is an alright fit both for the game and title. It is a bit jarring when the music switches at the start, so having a fade for the music would also help when changing songs (You are definitely not the first to do this). As far as sound effects go, your game doesn't seem to have a lot to put sound effects on so I'd say you got the most important ones, and they fit alright. That being said, when you stop the fire breathing, I think having it fade in/out would have felt much better than cutting it off instantly when you let go of E.
Last I want to go into the actual gameplay. With a concept this basic, it needs to be executed very well to actually be fun. Unfortunately I feel that the level design was as good as it could have been. For me and the couple of people I have seen try this game it was a bit to difficult, especially the second level. When I would lose it was hard to tell what I was actually doing wrong, which lead to repeating the same mistakes. Overall I think the levels are to long, and making them shorter would help make the game a bit easier and reduce the annoyance when starting over a.
In addition there's a lack of player feedback, particularly relating to visuals, that would have made actions feel more rewarding. I think having an extra animation or particles when getting fire or heating homes would have been nice. And while there is an indicator for when its getting dark and the chicken sound, more specific clarity to how far you are in a day would be nice (My first time playing I wasn't even sure if the first level was endless or completable, which could lead to some players not seeing most of your game).
One thing I will give you props for was the addition of a new feature each level. Although you only use them for surface level ideas, so having more interesting levels where you use the features in new ways or combine them would have been nice.
Overall the game checks every box on what it means to be a "complete game". It's the best game I've seen from you in a game jam, and I'm excited to see what you make next. I apologize if this review was a bit much, but I'm doing this to all the games from this jam as I think critiques help us grow
