Simply fun! It was nice to line 4 planets up. When I got close to lining them up I think of the meme,

I had a hard time playing without a controller though. It would be nice if the keys to speed up the planets were all next to each other in the same row on the keyboard. It was still quite fun to play and definitely would be a lot nicer with some ambient music. Good job man! Keep up the good work!
