4th Edition Early Access 3
Early Access Release 3 is now up on Gumroad, including two new levels (chapters) and some fixes for typos and unclear sentences. This includes a level solely focused on building some more significant programs, including Tic-Tac-Toe. (3rd Edition had a chapter called “Tic-Tac-Toe,” though this is substantially revised.) This release includes solutions to all of the challenges in that level since they are more substantial than others before it. (Eventually, they will all have answers.)
