I would love to give a higher rating after the bugs on the demo is fixed, I ran into roughly 4 bugs and one crashes the game with black screen of death. It does feel more beta than demo at the moment.
I have given my highlight record to the devs on twitter. https://www.twitch.tv/videos/1463742571
Overall love the premise, the art style, and the characters, I would love to try it again later.
Sound/music, animation are great, some small story moments even have illustrations which I thought was neat.
From the art side:
I would advise to cut a bit of the story scenes illustration workload later to help the project progress faster because without it, the game will still run fine and players not likely to miss it, you can save those details when you pitch it to be a TV cartoon show or storybooks. Otherwise, work the illustrations better into the game by adding some dialogues for the illustration storytelling, so it's not passing by the players in 1-2 seconds and hold their own weight as cut scenes.
It might be late but the dialogue font was a bit hard to read for me as a streamer, it's a very minor thing though.
