That's nice because it's a programming game, but it doesn't send you in the deep-end. Whatever you do appears on the screen pretty much instantly, so you get that constant feedback loop, it's like a 3D voxel REPL.

Many programming games got complex real quick and frankly annoying. I like this model, it's simple, if you let it through, it's a block, return a number for a colour.

It's a lot like shader programming. I guess one could argue it is shader programming.

Good point I didn't see it that way, but that's a perfect analogy.

And yet you can make it as deep as you like, thanks to the presence of leaderboard. In fact, some code golfers including me quickly jumped into the wagon ;-)

Add a 4th dimension, time, woo!
