I'm probably the 100th person to tell you this :) but this is a very unique concept and you guys did a good job at differentiating yourself from other jam games. The presentation is really well done with the simple but effective art, sound, and music.
I didn't derive that much enjoyment from the gameplay as in some other top jam games, but I think that's because I'm looking for a more involved gameplay experience - I think your game is for a particular audience and you cater to that audience well, I'm just not part of that audience. That being said, just sitting and listening as the stars go by is very soothing. I wouldn't be surprised if you guys get a very high rank in presentation and originality.
I am really nitpicking here, but the only piece of feedback I could think of is maybe the onboarding process for the game could be a little more intuitive. It's a little confusing what to do in the game initially and a lot of player do not want to have to read text starting out. Again, that's a minor thing. Overall great job.
I would love to get your rating / comments on my game as well so I can know what to improve.
