I had a hard time getting past the start menu. I'm playing on an ultrawide screen, so there could be some problem with the anchoring of the UI elements? I had to click blind on the side of my screen and finally hit the start game button.
I liked the gravity system the planets had and it was fun to go explore but once I died, the distances felt a bit long when you had to make the trip again. Anyway, once I saw the enemy, it got a genuine "oh shit" out of me. That being said, the enemy was pretty easy to dodge.
I wasn't entirely sure what I was supposed to do, and once I died the second time, I couldn't bring myself to go explore the planets a third time since that would've forced me to make the flight once again.
