Should a game jam host be able to submit their own game? It feels like there's a conflict of interest here.
Of the game itself: I thought it had a nice progression system and it was good for some cathartic fun, but I felt there wasn't enough feedback on the logic behind destroying planets. Is it based on the size of the object you knock into it? Do you deal damage over time or is it only destroyed if you meet a threshold with a single attack? I think adding some cracks to weakened objects would help convey this system better.
Also, I personally could not stand the music, all atonal bleeps and no melody. It sounds like the kind of thing I made before I learned music theory.
Sorry if this came across as harsh, I see something great here and would just like to bring it to its full potential.
