I played this game right through to the end. It was nice and relax after a few days of "lots of family!"
I loved it. I liked the vibe, the music, the art. I did hit a bug where I couldn't purchase the 6th song. The button was unresponsive, so I just saved up enough to by the 7th and played it and won.
The economics were a little weird. The regular fireflies lost meaning after a while. I amassed so many so fast. So any time I built a stall I could just upgrade it immediately. It made them feel relevant. Also, once I needed blue, the regular ones lost meaning entirely. Because I always had enough, so I focused on Blue, and the same thing happened with the red.
Overall though, super cute chill game. I played it all the way through this late into the jam, I think that speaks volumes. Solid work. I'll be following you!

Also, the theme and special object were used excellently.
