ah! The yang character feels so great to speed around as. It's a little messy control wise at first since they are so fast but once you get it down it truly feels great. There's tons of little things with the movement that I felt myself getting better at and wanting to get better at. There's even little tricks that are fun and most likely not intended but using the momentum from yang to fling the monk when you transform back.
The the movement of the camera in the world feels great too. The parallax looks quite nice and the zooming in and out is just pleasant to see.
The one rough spot (but not even much of a bad spot!) was that the yin character has just so much less moments of giving the player fun things to do. They have their one mechanic and they stick to it. I understand why it would be difficult though trying to make an opposite to yang.
Either way though I had a pleasant time going through this. :>
