I'm a Master of the Mind

My platforming game was a failure. Soon after I got started, I remembered how annoying it is to work with pixi.js, and I decided against making the platformer. Instead, I decided to make 1 or 2 smaller games. My first game that I'm making is Mastermind. I initially was going to use Hexaflip, but then I realized that Hexaflip was really poorly documented and was very buggy. I've made Mastermind using Vanilla JS instead. It's live at http://eli.gukovsky.com/mastermind.html right now
