I played this for a solid 30 minutes and have only made it to the big planet.
I love the aesthetic and sound design, the controls and mechanics are great and well thought out. I feel as though the game is too unforgiving , the Lose all progress if you mess up is nuts. I don't like the gravity to planet mechanic either since you cant tell when the gravity can kick in. maybe a visual would help.
Overall Great Aesthetic, intuitive controls and follows the prompt pretty well.
