Thank you so much for making this <3. I loved/hated the unicorn story especially. I was screaming internally, "you can be the unicorn!!!"
In terms of game-feel so much of this was so polished as well! The stars orbiting with sparkly particle effects, the woosh of the stars as you send them to their constellations, the gentle camera repositioning when you look back on the planet..the text boxes and font seemed perfect, the audio just meshed with everything as well.
Were the constellations 3D sprite billboards at the end there? Was thinking it might look better to have them two-sided so you can see the images even when looking down on the backside of them as well.
Overall, very well done, indeed!
