This was really well done! I use flexbox all the time and ended up finishing every wave with a score of 100, but even I learned some stuff. In practice, I've pretty much never used the `order` property even though I've always vaguely been aware of its existence. I've had to use `align-self` on occasion, but it's still something that I rarely touched and would have to lookup or mess around with any time I needed it. The forced need to use these rules for purposes of the game really helped drill the concepts home and I think I can confidently say that I'm now more comfortable with using flexbox for things without needing to open up documentation or alignment cheatsheets anymore. Nice work! I really appreciate the value this has and will definitely be sharing it with anyone else I know who uses flexbox on a day to day basis. I think it'd be awesome if you expanded more levels to incorporate concepts like flex-grow/flex-basis and whatnot.
