Space Invaders

I burned through all of my extra lives in a matter of minutes, and my two least-favorite words appeared on the screen: GAME OVER (Ernest Cline, Ready Player One)

Inspired by the book I read this summer and by this previous post, I decided to draw these aliens:

Invader1 Invader3
Invader4Invader2
