I love how stylish this is! That really works well for this game because, despite it simple gameplay, everything really pops! The background especially is just pleasant to look at, and still sells the idea of outer space nicely in my opinion.
Not sure I've got much feedback for this one; I think it does everything that it sets out to do really effectively. I'm not a huge fan of the font, but that's nitpicking and awfully subjective.
Overall, great work!
