This game didnt really utilize the limitation much. It seems like that the games theme was mostly Autumn and "Staying Warm" was just added at the end. Since this is a visual novel the art and story are highlighted much more and this is great art for your first jam as the characters are in different poses which reflect their personalities. There are a few things that can be improved such as the characters having different clothes and more detail and shading in the backgrounds (similar to the amount of love you give to the characters), but this is more nitpicky. Another nitpicky thing is the music, as the cozy tune was a good choice, but the music was more cafe cozy instead of cozy at a farm with rustic instruments or cozy country style music. Again this is nitpicky but something to be aware of. The great thing about Itch is that there are lots of independent artists and musicians where you gat get assets (sometimes for free) to not only expedite the game dev process but also allow you to focus on your strength (such as writing and character design) while mitigating weak spots. I do this all the time as my strength is in coding and utilize itch for music and art. Overall, great start to jamming and I'm excited to see what you do in the future :)
