This is a really awesome game that I was informed of the other day.
Basically the premise is this: You have a 2D topdown, tile based world where you have some control over the code that runs in this game. You have to use this to your advantage to defeat different levels.
I really suggest you check it out, even though I don’t know JavaScript whatsoever, I could figure out enough to get to Level 18, which I’m working on now.
