I enjoyed your game. It was easy to understand and the controls were intuitive. The music helped set a relaxing vibe and the black hole effect was well done. It would have looked better if the planets were more round (less pixelated).
Thank you for playing, TX Brothers! I was afraid it could be tricky to understand the mechanics, glad to hear that.
It was a personal stylistic choice to use pixel art and give it a sense of 3D, but maybe vector art could give a better feeling. Thanks again for the feedback!
