Interesting game with a really distinct art style!
Gameplay: The idea is fun, but there are some design decisions that seem a bit off. For example- when I discovered the first constellation it looked like I thought that was it. The screen doesn't indicate that I'm gonna be searching for another one now. I was about to turn off the game and start my review with "really short game" :) It's a pretty chill experience.
Audio + graphics: The graphics have a really distinct style, and the text animations look really well (not often I compliment text animations, but here we are). Not much happening with the audio, but the music fits the chill atmosphere really well.
Theme: I'll be honest here. It feels like you really wanted for the theme to be "roadtrip" and had a cool idea about a game with a plane. The star part feels a bit "glued on". I mean... I get it. I had a really cool idea for "roadtrip" :)
Over all. The elements that work, work well. Other parts need some polish.
Also- one more thing. I'd loose the AI- looking thumbnail. Your game looks stylish as it is, so use a screenshot instead.
