Thank you for playing!
Regarding gravity, I plan to visually display the gravity and velocity exerted on planets in the game in real time using arrows, hope that will display the gravity better
Regarding the judgment of looping, there's currently a bug: if the circle drawn is too large, it won't be recognized. I'll fix it as soon as possible.
Regarding the art, I will continue to refine it. The 4 days of Game Jam were really too rushed.
