I just made an account to leave this comment, and I'm not really good at speaking English because it's not my main language. But I wanted to leave a comment anyway, so I hope that's enough comprehensive. Sorry if my vocabulary can look poor; that's because it is the case.
I really loved your game. That's only the demo, but everything is great. The music is catchy and not annoying even if we hear them a lot, the sprite are messy (in the good way!) and creates an ambience that's similar to games that I really enjoy, like Omori or Yume Nikki. It was short and enjoyable, I absolutely love it and I crave to see more.
That's because I want to see more that I hope that in the full game, there's more interaction with the environment or between the characters. The dialogue with the PNJs are quite funny, and I was sad when I tried to talk with something or someone but there were no textboxes.
The story isn't really deep, that's not a critic, but I find it more interesting for its atmosphere than for what is happening. The adventure between fairies friends is enjoyable, but I kind of forget what I was doing for a moment sometimes.
Also, at the end of the demo, I encountered a bug where the dialogues were playing twice in a row, but the second time I was in the altar resting with the other fairies. I don't know if I'm the only one to have seen this bug, or if this will be corrected in the finale game, but I prefer to report it.
Overall, my opinion is really positive ! It was a chill experiment, and it was really what I needed. I love to play indie games because there's always a gem like your game, and like I already said, I crave to see more.
