Minor UI update

Made some minor UI changes in order to make it look less like AI slop - let me know if its good and what should I change!

Future changes:

• Make some galaxies float by in the background to add some visual spice
• Add more functionality to the thought stars (Like making them collide!)

Remember, you can always try it out here:

Make some suggestions in the comments for what I should do!
