Hi Marcelo, thanks for the feedbacks! It is nice to hear it from a fellow brazilian game dev pro.
As you can see no one besides myself play tested the game. I used rigidbody drag, so I could use velocity to end the turn and also to make the gravity field feel stronger.
Of course it is not meant to be like the "real" thing (what is real, maybe it is all a simulation, right?), but I didn't thought about how this would affect the gameplay, jsut like many other things.
I set the scale of the gravity fields to be always twice the radius of the planet for the sake of simplicity, but maybe making it non-linear would feel better.
I am not sure if I will keep updating this game after the GJ, but I will take your feedbacks for the next ones!
