Really cool game! I think the concept felt pretty original, but intuitive as soon as I started playing :) . I think the idea of being a kind-of-evilish alien being that sucks up planets is fun.
I like that the game is built around a simple but really fun core concept, and the mechanics all feel intuitive with the set dressing of the alien planet-sucking orbits. I could feel myself picking up some handy strats the more I played. Also, the music was really nice especially on level 3 (I couldn’t get farther), and I liked how colorful and different the planet styles were!
My biggest complaint is that I reset to level 1 when I die :( . I died at level 3 three times, so I felt too demoralized to try again lol. Maybe a lives system would be good so you can try the same level again a few times before resetting back to 1.
