Build 100 is now available for early access players. This adds 4 new levels which will teach you about arrays.
I've also added a "challenge" section at the end, and moved a few earlier levels there. These levels were a fair bit harder than the others. This way they dont block progress.
I'm planning on adding a hinting system to the game, to make it less likely for players to get stuck on any one level.
Have fun!
