Thanks a lot for your feedback! In hindsight I should've probably playtested more to perfect the gameplay loop but oh well, I spent way too much time making the actual game haha (and making the stars look pretty).
I didn't want to add a warning mechanic so as to always keep you on edge so I only included a highlight feature to keep that moment of "OH SHIT, THAT ONE'S WAY TOO CLOSE".
Also I played your game and it was one of my favourites in the jam, great job on that!
P.S. There are some easter eggs when you reach higher numbers of days btw ;)
