Easy to follow
Format: Paperback
My children are able to follow along. Directions aren't too simplistic nor too complicated. Good for adults too. They are using the skills they learned and adding new ones. Happy with this purchase.

Maybe Outdated
Format: Paperback
I got this for my brother who is attempting to make a game in Roblox. He said a bit of the information doesn't match the current game-making system, but that the book does have a lot of good information regardless.
