It was removed, it felt like such an unfinished feature and didn't quite make sense because players could never know what counted for the score. Instead you have a crystal and time record saved, so you can race to beat your own records or compare with others if you'd like :)
The original tutorials would take several months of dedicated programming work to implement, and it was decided it is too much effort just to replicate those when they wouldn't be very useful to the average player. They might happen in the future, but I would not bet on it, as the existing tutorials do the job fine considering all the new features that need to be explained.
