thank you for your valuable feedback, yes it definitely requires a good intuition for newtonian physics. we’ll look into how to make hitting planets easier without removing the challenge for experienced players (maybe we can generate more predictable orbits for the easier difficulties). With some more optimisations it might be possible to predict the flight paths a few seconds ahead. (the asteroid prediction uses a static estimation, making it super fast, but that only works because they are so light compared to the sun). Or we could teach the player more about how the planets move with a more extensive tutorial.
And i definitely have to tweak the difficulty assignment. Right now it switches players to harder difficulties way to fast.
