Hi there,

I recently stumbled across your repo. I've made a programming / puzzle game, and would appreciate it if you'd include it in your awesome list of games.

Lambda Spellcrafting Academy (LSA) is a programming game that teaches introductory programming, as well as some data structures and algorithms. The game uses a visual programming language, inspired by Lisp and modeled around arranging a hand of cards.
