I played a lot of levels until I realized it was randomly generated. That explains why some levels are stupidly easy while others are ok. As it is, the game's focus is more like "waiting for the orbits to align" than "using the gravity to steer your rocket to the goal".
Art's pretty. It's simple, but the lights and trails make it shine (heh). Music was well picked. I appreciate the nod to SUPERHOT.
The only thing that felt weird to me was that I expected to launch the rocket kind of like a slingshot, moving opposite to where I was pointing at. But it's not like that changed anything from the experience.
Overall, it's ok. It could use something like a score to compete with other players or something like that, to add some level of challenge.
