Very cool main character design! Also loved the falling effect on her.
Collecting the items was fun, but it felt a bit weird that some elements had SFX while others didn't. The song was catchy as well. I only found out at the very end that there was a score system?
I also think the background could have a bit more feedback (clouds move a bit more or just a timer/object counter in the corner) to make it feel like you are indeed progressing. Edit: Escape is also a weird key for menu as it defaults exits the fullscreen first, and on second press pauses.
The album is fantastic. Love having a place to see everything you collected! Chill playthrough overall!
