Surprisingly enjoyable, a little unforgiving but in a way that pushes you forward instead of making you feel like youre ramming your head against a wall. At least for a little while. My skill plateaued after a bit, leading to no progress, but it was very enjoyable while my skill was growing. 
Unfortunately, does not hold hand in any way shape or form, leaving you to figure out whats going on and what to do through trial and error.
