Thanks! I'll make sure to add those controls. (I used asd and space because my left hand is better at using the key board. But alright, i'll use arrow keys.) @Brezel the font I'm using is Lucida Console, it should be showing up without strange crowding and skips. And thanks. I could make it, but 20 frames is quite a lot xD. My character at most is using 7 frames. If you give me a reference picture, I ca give it a try.

Pretty good. It'd be even better if you have the planets be able to react to the other object's gravitational pull. And it'll be more accurate if you use leapfrog or some integration method to calculate the positions. Take a look at my Physics of Planets simulation. It might give you some ideas.

Very cool, my eyes started to hurt before all the dots went away, but it was very interesting in how a repeating pattern can trick our eyes into seeeing another thing.
