This is the most beautiful submission I've seen so far! The sense of scale is breathtaking! The audiovisuals are great!
I really wish I could say the same about the gameplay. I enjoyed sucking those stars in, but my ability to do so seemed very random. I found that it was better to restart a game and hope for a better start than wait and see if a star would come to you eventually. Sometimes I would get stars very early on, sometimes nothing for a few minutes. I don't mind the slow pace, because it fits the sense of scale, but the feeling that I had no control on my own success was a problem for me.
The controls are very unintuitive as well, and there are no instructions in-game. Seems like I needed to just hold W down, look at the stars closest to me, and hope for the best.
Also, wasn't sure how to avoid the other black hole. It would come for me once I started attracting a lot of stars. By the time I saw it coming, it was too late to do anything. I guess I'm supposed to repel it much earlier, but most of the time I couldn't see where it was so I didn't know if I was safe or not.
I complained a lot, but that's only because the game itself is amazing. I really am impressed with what you've accomplished here. I just want the gameplay to support the experience, not hinder it. Thank you for bringing this to existence.
