I sprung for the paid version, and have progressed part of the way through the last level. Compared to the demo, I think that it helped with some more advanced features, but mostly just made me aware of them rather than giving me the proficiency I learned with the basic commands. Perhaps if I repeated the game, I'd become more natural with them. Still, highly recommended. It's been a lot of fun to play, and it helped me to quickly become proficient.
