I had a tutorial but it felt too condescending so it didn't make it to the DD build. All that remains is the HOW book in the main menu.
If you check the keyboard shortcuts you will find that the speed up/down feature is marked as disabled. It was a little buggy for DD but it's definitely something I want to add.
The animations are in fact super fast because I always found myself disabling all animations a few hours into RPGs, even if they are cool. However, I have been told they are too fast before so that's probably something I'll do in the near future.
