Wow...this is incredibly beautiful in a way that I cannot succinctly describe, although I will do my best.
Even with it being a relatively short experience, I felt so many emotions that I cannot describe. The loneliness of self. Of nothingness. But also the beauty of life and creation. I loved the simplicity of the art and the poetic text. Everything was strung together in a way I can only describe as harmonic. The music also added a lot to the experience and was very melancholy.
I also really enjoyed being able to read the story of my universe at the end. It was very heartfelt.
One potential bug that I encountered was when the storms had disappeared from my sun. Because it was placed in the top right corner, the screen went to focus on the storms and then remained there. I couldn't move the camera and the rest of my beautiful universe could not be seen. :( I wish that I could've had the ability to pan across my entire universe.
Also, the black hole is incredibly powerful, although I think that it's appropriate for this scenario.
Just a beautiful concept. I love card games and I can see this becoming an indie icon after a bit of polishing. I will definitely recommend it to everyone that I can.
