Spirograph, The Game!
Seriously though, it's a fairly intriguing game.
The entirety of the game revolves (hah, wasn't intending that) around using gravity to complete an objective depending on the stage. These objectives vary from just staying alive and not crashing for a specific period of time, to flying through specific points on the map (using the gravity of static or moving bodies), to maintaining proximity to specific gravitational bodies.
The UI of the main menu leaves a bit to be desired, favoring artistic beauty over simplicity/clarity; from what I can infer, the idea is a pseudo-3D look, but in reality it all just looks blurry and out-of-focus. However, the actual gameplay doesn't suffer from these problems.
Another drawback of the game is that it is very CPU intensive. I currently have a Intel G3258 CPU in my computer that I've over-clocked, and any time I even attempt to go over minimum quality settings, my computer starts to noticably chug.
At the end of the day though, I had a quite enjoyable time. The mechanics are SPOT-ON and, although it seems the dev missed the mark when it came to the menus, the artistry of the actual gameplay is quite mezmerising at times. As long as you're not expecting anything genre-defining or ground-breaking (as most levels are pretty much variations-on-a-theme), you should have a pretty good time!
