I'm always a fan of gravity mechanics like this. Overall this game plays pretty darn well. I do wish the gravity didn't "cut out" at the dotted lines sometimes as it felt like I would have hit a stable orbit if the moon kept going. The last level, while it enticed me to play until I beat it, felt a little bit tedious only because it's hard to reproduce your shots so you can dial it in (I ended up using the stars in the background as reference for lining up my shots.
The music is good and fits well, but it does get a little repetitive after listening to it for 15 minutes :) Since it's mostly all I'm hearing when playing, keep that in mind for future games.
Overall a very clean entry mechanically and artistically. Definitely among the most pleasant games I've played this jam so far!
