this revealed my kid did not get the concept of "turning left" on a 2d grid

they put a lot of effort into making it relevant/exciting for a lot of kids. A lot of it is turtle like, in describing the steps to move a famous character, but much of it can be free form and the use of blocky/JS allows for an interesting intersection. Before my eldest could comfortably just read, the block interface was intuitive enough to piece together the ideas. Blocky is pretty neat.
